PREFACE. 


In  publishing  the  following  pages,  I do  not 
pretend  to  offer  original  matter ; but  merely 
an  abstract  of  a great  deal  that  has  been 
written  about  Vesuvius ; and  if  I should  ex- 
cite in  travellers,  who  may  visit  that  cele- 
brated Volcano,  an  interest  in  its  historic  and 
topographic  details,  and  prepare  them  to 
receive  and  bear  away  impressions  that  may 
be  instructive  and  lasting,  I shall  have  ob- 
tained the  object  I have  principally  had  in 


view.

VESUVIUS. 


“ I climb  a hill  of  ashes  at  whose  top 
A gorge  descending  leads  into  thy  home, 

Great  fire  ! where,  ’mid  thy  swarthy  realms  sublime. 
Under  a canopy  of  surging  clouds, 

On  thy  red  throne  exalted,  terrible, 

Thou  art  sole  master ; and  supreme  hast  been 
For  ages,  unopposed.” 


Among  the  enchanting  features  of  the  far-famed 
scenery  around  the  Bay  of  Naples,  the  favoured 
region  of  poets,  none  is  more  attractive  than  Ve- 
suvius, “ the  burning  mountain,”  which  has  allured 
the  curious  and  learned  in  all  ages,  and  from  all 
countries. 

This  mountain  has  two  summits : they  are  the 
present  cone  of  Vesuvius,  and  the  Monte  Somma. 
They  stand  on  a common  base,  bounded  on  the 
north  and  east  by  the  plain  of  the  Terra  di 
Lavoro,  which  separates  it  from  the  Appenines ; 
on  the  south  it  is  washed  by  the  sea;  and  on 
the  west  it  may  be  said  to  unite  with  part  of  the 
acclivity  on  which  Naples  is  built.  In  fact,  the 
division  between  the  extreme  western  slope  of  the 
Somma,  and  the  eastern  end  of  the  hill  called 


B

Poggio  Reale  of  Naples,  is  so  small,  that  it  can 
scarcely  be  considered  as  a physical  separation. 

The  ridge  of  the  Somma  forms  a semicircle,  the 
curve  of  which  lies  north-east,  its  two  extremities 
stretching  out  south-west ; and  it  is  a curious 
fact,  ascertained  by  Visconti,  that  the  diameter 
drawn  from  its  western  point,  near  the  Hermitage, 
to  its  eastern  termination  above  Mauro,  passes 
exactly  through  the  centre  of  the  present  crater. 
The  front  of  the  Somma,  which  faces  the  south- 
west and  the  cone  of  Vesuvius,  is  almost  perpen- 
dicular; but  the  side  towards  the  north  is  a sloping 
plain,  cut,  lengthwise,  by  deep  ravines,  and  covered 
with  vineyards ; except  a few  hundred  feet  near 
the  summit,  which  are  clothed  with  small  chesnut 
and  oak  trees. 

A narrow  valley  (called  the  Atrio  del  Cavallo  on 
the  west,  and  the  Canale  dell’  Arena  on  the  north,) 
divides  Somma  from  the  cone  of  Vesuvius.  The 
lava,  which  sometimes  flows  from  the  north  side  of 
the  cone,  the  scoria  and  ashes  that  are  ejected  or  are 
washed  down  from  it  into  this  valley,  raise  the 
level,  and  probably  will  some  day  fill  it  up ; and 
then  that  side  of  the  cone,  united  with  the  ridge 
of  the  Somma,  will  become  part  of  the  flank  of  the 
mountain. 

The  cone  of  Vesuvius,  in  appearance  a mass  of 
ashes,  is  truncated  from  n.e.  to  s.w.  and  rests,

on  the  north-west,  upon  the  Atrio  del  Cavallo ; on 
the  north-east,  upon  the  Canale  dell’  Arena ; and 
towards  the  south,  upon  the  Pedementina,  ex- 
tending its  flank  down  to  the  sea,  and  forming  an 
inclined  plane  from  its  vertex  to  its  base.  The 
slope,  from  the  Pedementa  and  the  Atrio  del  Ca- 
vallo, is  regular,  and  is  covered  with  vineyards 
and  gardens  : it  is  broken  only  by  the  Vocoli,  or 
small  cones  formed  during  the  eruption  of  I76O, 
by  the  picturesque  hill  on  which  the  convent  of 
the  Camaldoli  is  built,  and  by  prominences  raised 
on  the  lava  of  the  eruption  of  1794,  near  the 
Piano  delle  Ginestre.  On  the  north-west  side, 
it  is  cut  by  two  large  ravines,  separated  from  each 
other  by  the  ridge  of  the  Canteroni,  on  the  summit 
of  which  is  situated  the  hermitage  of  Saint  Janua- 
rius,  or  San  Salvatore.  The  ravine,  on  the  north, 
is  the  Fosso  Faraone,  running  n.w.  and  s.e.  ; that 
on  the  south  is  the  Fosso  Grande,  of  which  the 
direction  is  west  and  east.  The  lower  parts  of  the 
mountain  are  studded  with  towns,  villages,  and 
palaces,  that  rise  among  vineyards  and  gardens, 
the  property  of  men  who  forget  their  danger  while 
seeking  to  derive  wealth  from  the  fertility  of  its 
soil,  though  there  has  not  been  a period  of  a hun- 
dred years,  in  which  some  part  of  the  lands  around 
the  base  of  Vesuvius  has  not  been  ruined  by 
earthquakes,  destroyed  by  currents  of  lava,  or

covered  with  ashes.  But  what  is  there  with  which 
man  will  not  familiarise  himself?  The  eruption 
over,  the  inhabitants  return  to  build  their  houses 
on  the  same  spot  where  terrible  experience  ought 
to  have  made  them  dread  the  risk  of  being  buried 
by  some  future  eruption. * 

The  town  of  llesina  is  the  place  from  which 
those  who  visit  the  crater  are  commonly  conducted 
to  its  summit,  and  the  usual  route  from  that  town 
leads,  very  nearly  in  a straight  line,  towards  the 
north  side  of  the  cone,  until  it  reaches  the  Piano 
delle  Ginestre,  where  it  turns  off  to  the  left. 

The  “ Piano,”  once  adorned  with  evergreen 
shrubs,  bushes,  and  broom,  flowering  throughout 
the  year,  and  wearing  the  semblance  of  eternal 
spring,  now  presents  only  a desolate  expanse, 
wherein  nothing  is  seen  but  the  scorious  surfaces 
of  vast  streams  of  lava,  which,  in  pouring  down 
from  the  cone,  have  intersected  and  covered  each 
other,  have  been  heaped  up  in  confused  masses 
and  hillocks,  or  extended  in  broad  and  irregular 
ridges. 

The  time  occupied  in  getting  hither,  is  about 
an  hour,  and  the  road,  passing  between  vineyards 
protected  by  stone  walls  or  mud  banks  ( amacera ), 
is  wholly  uninteresting,  except  at  a few  spots 

* For  much  of  this  description  of  Vesuvius,  I am  indebted  to 
Breislak.  (Topografia  Fisica  della  Campania.  Cap.  iv.  7.)

where  one  obtains  some  beautiful  glimpses  of  Na- 
ples and  the  intervening  country,  through  breaks 
in  the  foliage  of  the  thickly  planted  vines. 

I have  generally  preferred,  and  I strongly  advise 
others,  to  make  the  ascent  in  the  direction  of  the 
Fosso  Grande,  by  a road  that  joins  the  one  already 
described  on  the  Piano  above  mentioned,  imme- 
diately before  it  arrives  at  the  great  ridge  or  hill  of 
the  Canteroni.  This  course  lengthens  the  time 
required  for  the  ascent  by  about  half  an  hour,  but 
the  path  is  less  difficult  and  steep,  and  is,  in  every 
respect,  better  than  the  other,  except  a few  yards 
of  the  latter  part  of  it,  which  must  be  performed 
on  foot.  It  has  the  great  advantage  of  a con- 
stant change  of  scenery,  and,  at  the  same  time, 
it  exhibits  a section  of  the  mountain  that  lays  its 
structure  open  to  the  view,  which  cannot  fail 
to  afford  both  pleasure  and  instruction  even  to 
unscientific  admirers  of  Nature. 

At  a short  distance  from  Resina,  this  second 
route  turns  off,  to  the  left,  from  the  line  of  the 
first,  and,  passing  between  vineyards  and  orchards, 
the  trees  of  which  generally  extend  their  boughs 
over  the  pathway,  making  in  many  places  a shady 
avenue,  reaches  some  streams  of  lava  which  came 
down,  through  the  Fosso  Grande,  and  ran  to 
St.  Jorio,  in  1767*  It  crosses  these  close  to  the 
small  chapel  of  St.  Vito,  built  near  the  site  of

another  that  was  destroyed  by  one  branch  of  the 
lava  of  the  above-mentioned  eruption,  and  it  is 
again  continued  under  the  shade  of  large  trees, 
until  it  comes  upon  the  principal  stream  of  1767  : 
proceeding  then  .between  its  two  walls  or  ridges, 
of  which  it  follows  the  direction,  it  soon  enters  the 
Fosso  Grande,  where  it  approaches  a small  cliff  of 
old  lava,  almost  concealed  by  the  wild  fig-tree,  by 
ivy  and  various  beautiful  evergreens,  that  hang 
about  it. 

At  some  distance  forward,  a bold  precipice  of 
tufo  and  lapillo  rises  on  the  left  hand,  and  from 
the  base  of  it  a gentle  slope,  covered  with  vines, 
extends  to  the  road.  On  the  right,  various  su- 
perincumbent beds  of  ancient  lava,  with  narrow 
intervening  strata  of  sand,  present  a perpendicular 
front,  the  brow  of  which  is  clothed  with  trees  and 
shrubs. 

Such  is  the  precipice  of  lava  represented  in  the 
accompanying  sketch ; which,  though  the  most 
picturesque,  is  not  the  highest  part  of  the  line  of 
precipices  that  compose  the  right  bank  of  the 
Fosso,  throughout  its  whole  length. 

The  path  leads,  next,  to  a very  steep  ascent 
over  the  hard  surface  of  an  old  stream  of  lava.  A 
few  minutes  suffice  to  climb  it,  when  the  view 
suddenly  opens : the  whole  plain  of  the  Ginestre 
appears,  with  the  black  cone  rising  at  its  further

end;  and  the  eye  which,  not  many  moments 
before,  dwelt  with  interest  on  the  effect  of  ancient 
eruptions,  now  regards  with  astonishment  the  work 
of  desolation,  produced  by  those  of  recent  occur- 
rence. 

The  route  here  unites  with  the  common  one, 
quits  the  lava,  and  ascends  towards  the  Hermitage 
through  a winding  cleft  in  the  mass  of'  lapillo,  of 
which  the  ridge  of  the  Canteroni  is  principally 
formed.  Before  arriving  at  the  upper  part  of  it, 
we  have  a magnificent  prospect,  which  extends 
over  the  great  and  richly  wooded  plain  of  the 
Campo  Felice,  stretching  one  way  as  far  as  to  the 
sea,  and  another  to  the  chain  of  the  Appenines 
behind  Caserta. 

The  Hermitage  of  San  Salvatore  (St.  Janua- 
rius)  is  situated  on  a small,  flat  space  at  the 
western  extremity  of  the  ridge  of  the  Canteroni. 
I have  in  vain  endeavoured  to  ascertain  at  what 
period  it  was  erected ; but  it  was,  probably,  imme- 
diately after  the  great  eruption  of  1631.  The 
building  contains  a chapel,  and  a few  rooms  for 
the  use  of  the  monk  or  hermit  who  resides  there 
throughout  the  year ; and  it  also,  of  late,  has  been 
used  as  a post  for  the  police  who  protect  it,  as  well 
as  the  persons  who  ascend  the  cone. 

Leaving  the  Hermitage  to  the  left,  the  road  lies 
along  the  highest  part  of  the  ridge,  at  the  end

of  whose  verdant  bank,  the  ashy  cone  rears  itself 
aloft,  with  white  smoke  rising  in  opaque  masses 
from  its  centre,  and  curling  high  into  the  air.  On 
one  side  the  view  extends  over  the  wild,  barren 
field  of  lava ; and,  on  the  other,  is  intercepted  by 
the  termination  of  the  Somma,  covered  with  brush- 
wood and  small  trees,  and  sloping  into  the  Fosso 
Faraone.  A wooden  cross  has  been  erected  at  the 
eastern  extremity  of  the  ridge,  and  once  in  the  year, 
as  also  in  all  great  eruptions,  the  assistance  of  the 
Patron  Saint  of  Naples  is  here  implored  to  protect 
the  Hermitage  from  the  fury  of  the  Volcano. 

Below  this  point,  in  the  Fosso  to  the  left,  once 
existed  the  little  chapel  of  La  Vetrana,  which  was 
destroyed  by  the  eruption  of  1786,  when  the  lava 
poured  over  a precipice  of  sixty  feet,  near  the 
building,  in  a cascade  of  liquid  fire. 

A short  descent  leads  down  to  the  Atrio  del 
Cavallo*,  or  plain  of  lava,  and  the  road,  winding 

* The  name  of  Atrio  del  Cavallo  was  given  to  all  this  part  of 
the  mountain  long  before  the  16th  century ; because,  “ in 
those  days,  people  always  came  thus  far  on  horseback,  and  it 
served  as  pasture  ground  for  their  horses,  as  until  the  year 
1631  it  produced  herbage  and  trees.”  Since  that  period  it  has 
been  so  often  covered  with  lava  and  ashes,  that  it  has  never 
been  capable  of  cultivation. 

A plain  surrounds  the  base  of  the  cone,  and  that  part  of  it 
which  bears  the  name  of  Atrio  extends  from  the  ridge  of  the 
Canteroni,  and  the  western  end  of  Somma,  to  a point  in  a direct 
line  above  the  convent  of  Camaldoli.  From  this,  to  the  eastern 
extremity  of  Somma,  it  is  called  the  Pedementina  ; and  thence

among  rude  unshapen  masses,  towards  a spot  at 
the  base  of  the  cone,  whence  it  is  necessary  to 
climb,  on  foot,  its  steep  sandy  side,  lies  in  a chan- 
nel, between  two  streams  of  lava,  the  one  on  the 
left  having  issued  in  the  eruption  of  1821,  and 
that  on  the  right  in  1822. 

On  the  left,  at  a short  distance  from  this  spot, 
are  two  small  cones,  the  only  remaining  ones  of 
six  that  were  thrown  up  in  the  eruption  of  1821. 
The  greatest  of  these  has  been  named  after 
Coutrel,  an  unfortunate  French  suicide,  who,  while 
it  was  in  a state  of  activity,  threw  himself  into  it, 
on  the  16th  January  in  that  year. 

The  view  from  this  point  is  beautiful,  the  rough 
dark  foreground  of  the  lava  contrasting,  in  a sin- 
gular manner,  with  the  green  bank  of  the  Can- 
teroni,  the  rich  plain,  and  the  deep  blue  sea  far 
beneath ; and,  the  sloping  base  of  the  mountain 
being  lost  to  the  eye,  they  appear,  particularly  the 
latter,  to  come  in  close  under,  as  it  were,  to  the  foot 
of  an  immense  perpendicular  cliff. 

It  takes  something  more  than  half  an  hour  to 
climb  up  the  steep  zig-zag  path  that  leads  to  the 
top  of  the  cone  ; and  the  greatest  difficulty  met 
with  in  the  ascent  arises  from  the  uncertain  footing 
which  the  ashes  afford. 


between  Somma  and  the  cone,  until  it  joins  the  Atrio,  it  is 
known  by  the  name  of  the  Canale  dell’  Arena.

SKETCHES  OF  VESUVIUS. 


On  the  summit  a scene  is  presented  which 
almost  baffles  description.  The  field  of*  lava  in  the 
interior  of  the  crater,  enclosed  within  a lofty  and 
irregular  bank,  might  be  likened  to  a lake,  whose 
agitated  waves  had  been  suddenly  petrified ; and, 
in  many  respects,  it  resembles  the  mers  de  glace , 
or  level  glaciers  of  Switzerland,  although  in  its 
origin  and  materials  so  very  different.  It  is  inter- 
sected by  numberless  crevices,  some  deep  and 
wide,  others  long  and  shallow.  Here  one  sees 
masses  curled  and  twisted  like  cables,  there  large 
slabs  piled  up  in  various  angles  against  each  other  ; 
in  one  part,  a wide  table  or  platform ; in  another, 
a narrow  stream,  the  ripples  of  which,  in  pushing 
each  other  forward,  have  maintained  their  wavy 
form  for  a great  distance.  In  the  sea  of  ice,  the 
white  dazzling  surface  is  relieved  by  beautiful 
tints  and  various  shades  of  blue  and  green  ; in  its 
simulachre  of  stone,  the  bright  yellow  and  red  of 
the  compounds  of  sulphur  and  the  metals,  inter- 
spersed with  the  pure  white  of  the  muriate  of 
soda,  afford  a pleasing  contrast  to  the  brown  and 
melancholy  hue  of  the  lava. 

A small  black  cone,  formed  of  scoria  ejected 
from  its  mouth,  rises  from  the  lava  a little  to  the 
north-east  of  the  centre  of  the  crater ; and  from 
a cavity  in  it,  volumes  of  smoke  roll  up  into  the 
air,  sometimes  accompanied  by  a cloud  of  small

fine  sand,  and,  often,  by  showers  of  red-hot  molten 
lava,  which,  shot  aloft,  soon  scatter  and  fall  in  all 
directions ; a part  in  large  masses  like  cannon 
balls,  a part  in  small  perfect  spheroids,  or  in 
lumps  that,  striking  on  the  lava,  dash  out  into 
long  strings  of  scoria. 

Two  terraces  of  lava  extend  across  the  crater 
from  the  southern  side  of  the  small  cone,  and  upon 
them  several  conical  fumaroli,  lately  thrown  up, 
constantly  ejected  vapour  which  gushed  forth  with 
a hissing  noise.  One  of  these  had  been  rent  asun- 
der by  some  violent  convulsion  in  the  crater.  One 
half,  which  had  fallen  down,  presented  a confused 
heap  of  lava  in  cubical  blocks  ; but  the  part  that 
remained  standing  exhibited  a structure  like  that 
of  columnar  basalt,  and  the  whole  was  covered 
with  beautifid  crystallisations  of  the  salts  of  copper 
and  iron,  in  various  shades  of  green. 

The  shortest  way  to  get  to  that  part  of  the 
crater  which  is  above  Bosco  Reale,  the  lowest 
point  of  the  circumference,  is  to  proceed  across 
the  lava  ; yet  the  vapour  of  the  sulphuric  and 
muriatic  acids  is  sometimes  so  strong,  that  it  can 
be  passed  in  safety  only  by  hurrying  over  the  spot 
where  it  is  evolved,  and  taking  the  precaution  to 
cover  the  mouth  with  a handkerchief. 

Without  venturing  on  the  lava  no  idea  can  be 
formed  of  the  beautiful  combinations  of  colours  of

the  sulphur  and  metallic  salts  deposited  during 
the  continual  sublimation  effected  in  that  great 
laboratory  ; of  the  fantastic  shapes  into  which  the 
lava  is  moulded  in  oozing  out  from  the  crevices 
and  mouths  of  its  natural  furnaces ; of  the  manner 
in  which  the  fumaroli  are  heaped  up,  and  how  the 
vapour  issues  from  them  : in  short,  much  that  is 
interesting,  curious,  and  instructive,  is  only  to  be 
seen  by  going  to  the  centre,  and  by  a close  inspec- 
tion of  the  crater,  the  more  minute  objects  there 
discovered  being  lost  in  the  distant,  though  beauti- 
ful view  obtained  from  any  part  of  the  edge. 

Until  September,  when  the  lava  rose  to  its  pre- 
sent height,  it  was  necessary  to  make  the  circuit 
of  half  the  cone  to  reach  the  lowest  part  already 
described,  that  over  Bosco  Reale,  the  only  point 
whence  it  was  possible  to  go  down  to  the  lava  at 
the  bottom  of  the  cavity  ; and  the  descent  was 
accomplished  by  wading  down  a steep,  narrow 
slope  of  loose,  hot  ashes,  into  which  the  leg  sank 
up  to  the  knee  at  every  step,  always  causing  an- 
noyance, and  often  terror,  to  those  who  engaged 
in  the  hazardous  exploit  of  descending  into  the 
crater.  The  depth  at  this  part,  in  May  1830,  was 
seventy  feet;  by  December  following,  it  had  de- 
creased to  fifty ; and,  on  the  1st  of  last  September, 
it  was  only  ten. 

The  path  to  this  point  lies  along  the  tortuous

and  uneven  edge  which  forms  the  summit  of  the 
southern  side  of  the  cone,  and,  being  neither  diffi- 
cult nor  dangerous,  is  generally  chosen  in  prefer- 
ence to  crossing  the  lava,  particularly  after  dark. 
The  view  from  the  highest  peak  is,  perhaps,  one 
of  the  most  beautiful  in  the  world ; the  height  of 
the  mountain  not  being  so  great  that  the  features 
of  the  fairy  land,  over  which  the  eye  roves,  are 
either  lost  or  too  much  diminished. 

To  the  s.  e.  the  island  of  Capri  rises  from  the 
bosom  of  the  ocean,  like  a huge  fortress  protecting 
the  entrance  of  the  bay.  On  turning  to  the  left, 
one  sees  the  Appenines,  embosoming  Massa  and 
the  orange-covered  platform  of  Sorrento,  extend 
their  dark  line  along  the  shore  as  far  as  CastelF 
amare,  over  which  towers  St.  Angelo,  their  highest 
point.  Thence,  their  lofty  range,  dividing  the 
valley  of  the  Sarno  from  the  bay  of  Salerno,  runs 
up  into  the  country,  until  it  makes  a bend  to  the 
left,  and  forms  a distant  semicircle  round  Vesuvius 
and  the  plain  of  Nola,  which  spreads  out  between 
them.  Behind  Caserta,  these  picturesque  moun- 
tains hide  their  heads  in  the  clouds,  though,  at 
times,  their  grey,  and  often  snow-covered  summits, 
sparkling  with  the  rays  of  the  sun,  are  beautifully 
defined  through  the  clear  atmosphere.  Monte 
Circello,  and  the  hills  about  Gaeta,  terminate  the 
line,  again  lost  in  the  sea,  but  enclosing  the

luxuriant  Campo  Felice,  with  the  numberless  towns 
scattered  over  its  surface.  The  whole  tract  fenced 
in  by  this  line  of  mountains,  and  lying  between 
it  and  the  sea,  is  of  volcanic  origin,  and  to  it 
the  ancients  gave  the  name  of  Campi  Phlegraei. 
The  plain  is  perfectly  level,  till  it  reaches  the 
acclivity  on  which  the  city  of  Naples  rises,  terrace 
above  terrace,  each  built  of  palaces  and  churches, 
thickly  crowded  together,  and  crowned  by  the 
massive  walls  of  the  castle  of  St.  Elmo.  Behind 
these  is  a semicircular  hill,  splendid  and  verdant, 
whereon  villas,  gardens,  and  orange  groves  stand, 
one  above  the  other,  in  rich  confusion.  Farther 
on,  the  Camaldoli,  the  promontory  of  Posilipo,  and 
the  mountains  behind  the  bay  of  Baia,  raise  their 
heads  and  form  a fine  background  to  the  city.  To 
the  left  of  these,  the  high  conical  point  of  Ischia, 
frowning  over  the  island  of  Procida,  and  a long 
line  of  blue  sea  close  this  extensive  Panorama. 

From  the  highest  point  on  this  side  of  the  cra- 
ter, the  descent  is  rapid  to  the  s.  e.,  or  lowest  part, 
where  the  lava  flowed  over  on  the  morning  of  the 
18th  of  September.  The  surface  of  the  field  of 
lava  within  the  crater,  intersected,  on  that  day,  by 
various  streams  of  molten  matter,  presented  a 
beautiful  and  striking  appearance.  It  was  almost 
impossible  to  approach  close  to  the  running  lava, 
on  account  of  the  intense  heat ; but  I succeeded

in  getting  sufficiently  near  to  one  stream,  and  was 
enabled  to  remain  long  enough  to  push  a stick  into 
it,  and  ascertain  its  fluidity,  which  was  like  that  of 
glass,  when  taken  out  of  the  furnace. 

One  current  had  passed  over  the  edge  but  had 
cooled,  after  having  thrown  up  a mass  in  lage  flakes, 
to  the  height  of  15  feet,  but  so  disposed,  that  it 
appeared  in  regular  steps  of  five  feet  each.  Close 
to  the  right  of  this  mass,  a wide  stream  approached 
the  edge,  and  threatened  to  run  over ; hut  that 
also  cooled.  However,  soon  after,  a third,  nar- 
rower, and  more  to  the  right  of  the  others,  flowed 
rapidly  towards  that  part  of  the  circumference 
where  it  begins  to  rise  in  the  direction  of  the  Palo, 
and  in  running,  heaped  up  a line  of  black  scoria 
on  each  side,  as  the  ploughshare  does  the  mould 
through  which  it  cuts.  The  accompanying  sketches 
show  the  appearance  of  this  part  of  the  crater, 
about  two  o’clock  in  the  afternoon  of  the  18th, 
when  the  last  stream  had  just  attained  the  edge. 

During  the  whole  of  the  day  the  small  cone  was 
in  great  activity,  and  the  very  large  masses  of  lava 
and  scoria  ejected  from  it,  were  thrown  to  a great 
height.  The  smoke  was  very  thick  and  dark,  be- 
ing loaded  with  fine  black  sand,  which  fell  on  the 
Palo  and  that  part  of  the  cone  in  great  quantity. 

The  inequality  of  the  south  side,  and  the  ascent 
to  the  Palo,  the  highest  point  of  Vesuvius,  is

equally  steep  and  fatiguing,  whether  made  on  this 
side,  or  on  the  other.  The  view  from  it  is  not 
finer,  nor  more  extensive,  than  the  one  I have  de- 
scribed, and  the  only  advantage  it  has  is,  that  of 
presenting  more  distinctly  the  Somma  and  the 
Canale  dell’  Arena,  which  latter  is  a flat  semi- 
circular plain,  entirely  covered  with  fine  ashes, 
and  much  resembling  the  bed  of  a lake,  the  waters 
of  which  have  been  dried  up. 

On  the  evening  of  the  20th,  three  streams  of 
boiling  lava,  separated  from  each  other  by  a line  of 
scoria,  cooled  into  blocks  and  flakes,  and  closely 
cemented  together  by  lava,  flowed  down  the  ex- 
terior of  the  cone.  When  it  became  dark,  the 
appearance  of  these  currents  was  exceedingly  cu- 
rious, and  in  the  accompanying  sketch  I have 
endeavoured  to  represent  their  picturesque  effect. 
During  the  night  a column  of  melted  scoria,  of  a 
bright  red,  was  thrown  from  the  small  cone,  every 
half  second,  high  into  the  air,  accompanied  by  a 
white  smoke,  tainted  sometimes  with  a deep  scarlet 
colour,  sometimes  with  delicate  pink ; both  caused 
by  the  reflection  of  the  fire  within  the  crater. 

On  the  23d,  the  lava  flowed  out  in  several  places 
near  the  former  streams,  and  uniting  with  them, 
advanced  to  the  foot  of  the  great  cone.  It  went 
thence  in  an  easterly  direction  across  the  Pedemen- 
tina,  but  afterwards  changed  its  course,  turning  to

the  right,  and,  winding  for  a short  distance  round 
tiie  base,  formed  a smoking  track  on  its  south- 
eastern side.  Tiie  whole  line  resembled  fresh 
mould  piled  up  in  masses,  here  in  long  strips, 
there  in  small  hillocks : smoke  arose  from  the 
whole;  and  occasionally  a short  line  of  red  peeped 
out  from  the  dark,  dull  heap  of  scoria.  Some  of 
these  were  remarkable  : the  lava,  in  flowing  along, 
had  thrown  up,  on  either  side,  a thin  perpendicular 
wall  of  scoria,  and  between  the  two  banks  passed 
the  stream  which  issued  from  under  a perfect  arch 
formed  by  masses  of  scoria,  and,  having  run  twenty 
or  thirty  feet,  entered  under  another,  and  dis- 
appeared among  large  heaps  of  the  same  matter. 
Some  idea  may  be  formed  of  the  singularity  of 
one  of  the  channels,  from  tiie  accompanying  illus- 
tration. 

Satisfied  with  viewing  the  curious  features  of 
the  crater,  it  will  be  well  to  await  the  close  of  day, 
ere  one  commences  the  descent ; and,  if  the  weather 
has  been  fine  or  if  the  atmosphere  is  clear,  few 
will  quit  the  spot  without  beholding  a picture  of 
surpassing  splendour;  for  lovely  indeed  is  the 
prospect  when  the  scenery,  “ matchless  in  beauty,” 
is  illuminated  by  the  rays  of  the  setting  sun,  which 
clothe  it  with  lucid  softness,  or  dazzling  brilliancy. 
Often,  as  the  radiant  orb  gradually  approaches  the 
horizon,  and  sinks  into  the  sea,  a dark  mass  of

clouds  descends  over  it,  as  it  were  a pall,  which,  for 
a few  moments,  shrouds  its  departing  glory ; but 
soon,  clouds  and  mountains,  plains,  trees,  and 
towns,  in  short  every  thing,  becomes  saturated 
with  dark  orange  tints,  or  the  vivid  ones  of  the 
ruby,  or  those  of  the  delicate  rose ; the  bright  blue 
sea,  from  reflected  lustre,  showing  like  a flood 
of  liquid  gold,  its  burnished  waves  rippling  beneath 
the  fluttering  land-breeze  which  floats  gently  from 
the  shore,  while,  here  and  there,  some  boat  or 
speronaro,  with  fan-like  sails,  pursuing  its  solitary 
course,  casts  a faint  shadow,  on  the  bright  expanse. 
Slowly,  almost  imperceptibly,  the  golden  hue,  the 
roseate  dye,  fade  away,  and  the  veil  of  darkness, 
with  its  leaden  gloom,  descends  upon  the  scene. 

Night  closes  in  suddenly,  so  that  torches  are 
necessary  to  light  one  downward ; and,  instead  of 
following  the  winding  path  along  which  the  ascent 
was  made,  a track  is  taken  that  leads  in  a straight 
line  from  the  summit  of  the  cone  to  the  base,  near 
the  blocks  of  lava  where  the  mules  are  left*  : the 
descent  is  accomplished  in  a few  minutes ; for,  as 
the  ashes  are  deep  and  no  large  stones  are  in  the 
way,  it  is  both  a safe  and  easy  process  to  run 
down. 

The  appearance  produced  by  the  glare  of  the

torches  over  the  dusky  and  desolate  piles  of  lava 
among  which  the  road  lies,  is  wild,  singular,  and 
romantic,  particularly  so,  when  the  party  is  large 
and  furnished  with  many  flambeaux : the  beauty 
of  the  scene  is  much  increased  by  the  intermixture 
of  the  dark  cloaks  of  the  men,  with  the  party 
coloured  shawls  and  dresses  of  the  women,  the 
medley  of  horses,  asses,  mules,  and  their  uncouth 
drivers,  with  torch-bearers,  facchini  carrying  baskets 
on  their  heads,  and  half  clothed  stragglers  who,  in 
this  idle  country,  commonly  present  themselves  on 
every  excursion  in  which  a number  of  persons  are 
assembled.  The  effect  of  the  motley  groups, 
hallooing  and  screaming,  as,  moving  forward,  they 
wind  through  the  deep  cut  in  the  hill  of  the 
Canteroni,  below  the  Hermitage,  is  equally  strange 
and  picturesque. 

How  different  the  feeling’  of  the  traveller  when 
the  moon,  in  some  calm  evening,  throws  her 
silvery  light  over  the  rugged  scene,  faintly  illu- 
minating the  mountain,  the  plain,  and  the  glassy 
sea,  but  scarcely  disclosing  the  islands,  or  the 
range  of  the  Apennines,  except  as  shadows  in  the 
distance ! Slowly  and  silently,  attended  by  his 
mule  driver  or  guide,  he  proceeds  downwards, 
afraid  almost  to  whisper,  lest  he  should  disturb  the 
stillness  which  reigns  around,  and  break  the  charm 
of  this  impressive  solitude.

If  the  descent  is  made  in  the  daytime,  the  route 
may  be  changed,  with  much  advantage,  by  going- 
down  through  the  Fosso  Faraone  and  the  Nocelle. 
This  will  occupy  a little  more  than  two  hours  from 
the  Hermitage,  and  will  present  a very  different, 
but  still  a beautiful  aspect  of  the  mountain  and  the 
plain  that  skirts  its  base. 

The  path  leads  from  the  north  side  of  the  plat- 
form of  San  Salvatore,  and  winds  among  the  oak 
plantation  till  it  arrives  in  the  Fosso  Vetrana,  on  a 
narrow  space,  to  the  very  edge  of  which  the  over- 
running thickets  descend,  between  the  Somma  and 
the  Canteroni.  It  thence  passes  through  a narrow 
gorge  for  a few  paces,  when  the  eye  unexpectedly 
discovers  the  lower  parts  of  the  mountain,  the 
ridge  of  the  Somma  sloping  to  St.  Sebastian,  and 
the  plain  with  the  numerous  dells,  or  watercourses, 
which  intersect  it,  at  a depth  of  400  feet  below  the 
pass.  Every  part  is  completely  covered  with 
stunted  trees,  the  autumnal  clothing  of  which  casts 
a rich,  brown  hue  over  the  surface,  and  gives  an 
aged  and  forest-like  appearance  to  the  whole. 

The  road  continues  along  the  brink  of  a preci- 
pice which  overhangs  a considerable  space  of  the 
slope,  and,  gradually  descending  the  Pietra  di 
Cautril,  crosses  a path  which  runs  from  the  Her- 
mitage to  St.  Sebastian.  At  this  point  the  view  is 
very  lovely : the  Canteroni  being  covered  with 


SKETCHES  OF  VESUVIUS. 


‘21 


myrtles  and  other  evergreens,  growing  among 
large,  detached,  and  craggy  masses  of  tufo  or  ot 
lava,  have  a bold  and  rocky  appearance;  and  the 
Somma,  overspread  with  its  dun  and  leafy  garment 
and  tinted  by  the  bright  rays  of  the  sun,  affords  a 
diversity  of  colour  and  a profusion  of  light  and 
shadow,  which  heighten  the  picture  into  magnifi- 
cent effect. 

The  path*  then  enters  a cleft  eight  feet  wide 
and  twenty  feet  high,  in  the  solid  tufo  or  sand,  and 
continues,  for  some  distance,  between  its  perpen- 
dicular walls,  till  a break  occurs  in  the  southern 
side,  which  discloses  Naples,  hanging  as  it  were  in 
the  air,  for  the  intervening  country  is  concealed 
from  view.  The  path  then  becomes  more  narrow, 
its  sides  rise  higher,  and  instead  of  being  straight, 
it  follows  a serpentine  course.  Vines,  fruit  trees, 
and  shrubs  hang  over  the  cleft,  almost  shutting  out 
the  light,  and  its  edges  are  fringed  by  creeping 
plants  and  brambles.  After  ten  minutes’  walk  in 
this  cold  damp  passage,  one  comes  out  into  sun- 
shine and  into  the  open  vineyards,  through  which 
a good  road  leads  till  it  arrives  at  the  edge  of  a 
deep  ravine,  the  depth  of  which  is  at  least  80  or 
(J0  feet:  its  steep  sides  are  here  and  there  tufted 
with  enormous  aloes,  or  overgrown  with  ivy  and 

* The  name  given  to  this  part  of  the  route  is  the  Cupa  delle 
Nocelle.

luxuriant  bushes ; and  at  its  bottom  rolls  a stream, 
which,  after  rain,  becomes  a foaming  torrent,  as  it 
receives  a great  deal  of  the  water  which  descends 
on  this  side  of  the  mountain.  The  road  winds 
along  the  southern  side  of  this  dell  and  enters 
another  pass  in  the  tufo,  but  soon  issues  again  and 
joins  the  high  road  from  Portici  to  St.  Sebastian. 
Here  it  turns  to  the  left  and  proceeds  between 
stone  walls  and  hedges  enclosing  fruit  gardens  and 
vineyards,  till  it  crosses  a stream  of  the  lava  of 
I7C7,  the  principal  one  described  in  the  ascent 
through  the  Fosso  Grande.  It  then  again  enters 
a cultivated  district,  and  after  several  turns,  now 
to  the  right,  now  to  the  left,  arrives  at  an  isolated 
mass  of  lava  on  which  a cross  is  erected  ; whence  it 
immediately  passes  under  a bridge  that  connects 
the  Royal  Grounds,  and,  intersecting  them,  enters 
Resina  on  the  northern  side  of  the  church,  the 
opposite  side  to  that  which  was  passed  on  quitting 
the  town. 

It  may  be  proper  to  observe  that  several  parts  of 
this  road,  especially  near  the  Pietra  di  Cautril,  are 
in  bad  condition,  steep,  rugged,  and  unsafe  unless 
passed  on  foot ; but  the  rest  of  it  is  as  good  as  any 
of  the  other  routes. 

Having  thus  proceeded  from  the  bottom  to  the 
top,  and  again  from  the  summit  to  the  base  of  this 
celebrated  mountain,  and  having  described,  in  the

order  in  which  they  present  themselves,  the  most 
striking  parts  of  its  western  or  more  frequented 
side,  it  remains  for  me  to  hope  that  my  sketches, 
however  faint  and  imperfect  they  may  be,  will, 
nevertheless,  serve  as  a general  outline  of  Vesuvius 
to  strangers,  and  induce  those  who  have  the  op- 
portunity, to  fill  them  up,  by  personal  inspection, 
to  the  variety,  magnitude,  and  sublimity  of  their 
original.

“ Forth  from  whose  nitrous  caverns  rise 
Pure  liquid  fountains  of  tempestuous  fire. 

And  veil  in  ruddy  mist  the  noonday  skies ; 

While  wrapt  in  smoke  the  eddying  flames  aspire, 

Or  gleaming  through  the  night  with  hideous  roar, 

Far  o’er  the  reddening  main  huge  rocky  fragments  pour.” 


The  history  of  Vesuvius,  previous  to  the  com- 
mencement of  the  Christian  era,  is  involved  in  the 
obscurity  of  fable.  The  historians  and  geographers 
of  that  early  epoch  allude  to  its  eruptions,  but 
make  no  precise  mention  of  the  periods  to  which 
tradition  or  the  annals,  then  extant,  assigned  them. 
In  describing  the  appearance  of  the  mountain,  they 
have,  moreover,  given  no  clear  information  with 
regard  to  its  form,  so  that  we  are  uncertain  whe- 
ther, in  their  days,  it  rose,  from  the  base,  as 
a single  cone,  or  had  the  shape  it  now  presents  j 
though,  from  its  structure,  it  is  evident  that  the 
wall  of  Somma  and  the  ridge  of  the  Pedementina 
once  formed  the  circumference  of  the  cone,  the 


28 


ERUPTIONS  OF  VESUVIUS. 


height  of  which  was  probably  much  greater  than 
that  of  the  present  one  ; for  without  such  a sup- 
position “ the  original  crater  must  have  been  many 
miles  in  diameter,  and  more  enormous  than  almost 
any  one  known  on  the  globe.”* 

No  record  informs  us  when  that  part,  of  which 
the  Pedementina  formed  the  base,  was  carried 
away,  although  it  is  generally  supposed  to  have 
been  displaced  during  the  great  eruption  of  79 
A.  D.  ; Somma,  the  only  part  of  the  original  crater 
which  resisted  the  shock,  remaining. 

The  first  author  who  takes  notice  of  Vesuvius, 
is  Diodorus  of  Sicily,  and  he  states  “ that  it  had, 
in  former  times,  thrown  out  fire,  like  Etna,  and 
that  it  still  (25  years  before  Christ)  retained  many 
vestiges  of  ancient  eruptions.” 

The  next  is  Strabo,  who  wrote  about  seventeen 
years  B.  C.  After  giving  a description  of  the  local- 
ities of  Herculaneum,  Pompeii,  Nola,  Nocera,  and 
Acerra,  he  says,  “ Over  these  is  situated  Vesuvius,  a 
mountain  surrounded  by  very  fertile  land,  though 
the  summit,  the  greater  part  of  which  is  flat  and 
barren,  like  ashes  in  appearance,  contains  caverns 
full  of  holes,  and  stones  of  a dark  colour  as  if 
burnt  by  fire.  It  is  therefore  easy  to  conjecture 
that  these  places  formerly  were  ignited,  and  had

craters  of  fire  which  afterwards  became  extinct  for 
want  of  materials  to  consume.” 

Vitruvius,  fifteen  years  B.  C.,  recommends  an 
earth  (Pozzuolana),  found  about  Baja  and  the 
neighbouring  country,  at  no  great  distance  from 
Vesuvius,  as  being  a most  proper  and  durable 
cement  for  building,  under  water  as  well  as  on  dry 
land.  He  supposes  one  cause  of  its  excellence  to 
be  the  process  it  has  undergone  in  the  fire  which 
lies  below  all  this  district.  “ It  deserves  also  to 
be  mentioned,”  continues  he,  “ that  long  ago  fire 
greatly  increased  under  Vesuvius,  whence  it  arose 
and  discharged  flames  over  the  country  around.” 

This  is  all  we  learn  of  Vesuvius  from  those  who 
described  it  before  the  reign  of  Titus ; and  we 
may  suppose  that  if  the  summit  or  crater  had  not 
been  a sterile  plain,  while  its  sides  were  covered 
with  luxuriant  woods,  with  vineyards  and  gardens, 
it  would  have  presented  at  that  time  much  the 
same  aspect  as  do  now  Monte  Barbaro  and  the 
Astroni,  where  the  thickets  are  almost  impervious, 
and  forest  trees  grow  closely  together.  The  in- 
habitants of  the  populous  cities  around  it,  no  doubt, 
lived  in  fancied  security,  little  dreaming  that  a 
dangerous  element  lay  beneath  them  ; that  irresist- 
ible torrents  of  fire  were  ready  to  burst  out  from 
the  bowels  of  the  then  tranquil  mountain  ; and 
that  these,  in  their  precipitous  descent,  might

ERUPTIONS  OF  VESUVIUS. 


involve  them  all,  as  indeed  they  did,  in  one  com- 
mon destruction. 

The  first  portentous  sign  of  returning  vigour 
which  Vesuvius  gave,  was  an  earthquake  in  the 
year  03,  the  shocks  of  which  laid  in  ruins  most 
of  the  cities  at  its  base,  and  frightened  and  drove 
away  the  inhabitants  from  their  dwellings.  No 
sooner,  however,  had  the  terror  inspired  by  this 
convulsion  subsided,  than  the  people,  returning  to 
their  habitations,  proceeded  to  repair  them,  and 
to  rebuild  the  public  edifices. 

Sixteen  years  of  treacherous  quiet  passed  away, 
when  the  mountain  began  again  to  exhibit  its 
tremendous  activity,  during  which 

“ Clouds  quench  the  sun,  and  thunder-smoke 
Strangles  the  air,  and  fire  eclipses  heaven,” 

and  which  has  since  often  threatened  the  neigh- 
bouring  country  with  devastation. 

79  A.  D.  The  first  recorded  eruption,  that  by 
which  Herculaneum  and  Pompeii  were  buried, 
began  on  the  24th  August,  and  is  so  fully  described 
by  Pliny  the  younger,  in  two  letters  to  Tacitus, 
that  I cannot  do  better  than  by  inserting  them. 

“ To  Tacitus.* 

“ Your  request  that  I would  send  you  an  ac- 
count of  my  uncle’s  death,  in  order  to  transmit  a

more  exact  relation  of  it  to  posterity,  merits  my 
acknowledgments ; for,  if  the  glorious  circum- 
stances which  occasioned  this  accident  shall  be 
celebrated  by  your  pen,  the  manner  of  his  exit 
will  be  rendered  for  ever  illustrious.  Notwith- 
standing he  perished  by  a misfortune,  which,  as  it 
involved,  at  the  same  time,  a most  beautiful  country 
in  ruins,  and  destroyed  so  many  populous  cities, 
seems  to  promise  him  an  everlasting  remembrance  : 
notwithstanding  he  has  himself  composed  many 
works  which  will  descend  to  the  latest  times ; yet, 
I am  persuaded,  the  mentioning  of  him  in  your 
immortal  writings  will  greatly  contribute  to  eternize 
his  name.  Happy  I deem  those  to  be,  whom  the 
gods  have  distinguished  with  the  abilities  either 
of  performing  such  actions  as  are  worthy  of  being 
related,  or  of  relating  them  in  a manner  worthy  of 
being  read ; but  doubly  happy  are  they  who  are 
blessed  with  both  these  uncommon  endowments  : 
and  in  that  number  my  uncle,  as  his  own  writings 
and  your  history  will  prove,  may  justly  be  ranked. 
It  is  with  extreme  willingness,  therefore,  I execute 
your  commands ; and  I should,  indeed,  have 
claimed  the  task,  if  you  had  not  enjoined  it.  He 
was,  at  that  time,  with  the  fleet  under  his  com- 
mand, at  Misenum.  On  the  24 th  of  August, 
about  one  in  the  afternoon,  my  mother  desired 
him  to  observe  a cloud  which  appeared  of  a very 


32 


ERUPTIONS  OF  VESUVIUS. 


unusual  size  and  shape.  He  had  just  returned 
from  enjoying  the  benefit  of  the  sun  ; and  after 
bathing  in  cold  water,  and  taking  a slight  repast, 
was  retired  to  his  study  : he  immediately  arose, 
and  went  out  upon  an  eminence,  from  whence  he 
might  more  distinctly  view  this  very  singular  phe- 
nomenon. It  was  not,  at  that  distance,  discernible 
from  what  mountain  this  cloud  issued  ; but  it  was 
found  afterwards  to  proceed  from  Vesuvius.  I 
cannot  give  you  a more  exact  description  of  its 
figure,  than  by  resembling  it  to  that  of  a pine-tree  ; 
for  it  shot  up  a great  height  in  the  form  of  a tall 
trunk,  which  spread  at  the  top  into  a sort  of 
branches ; occasioned,  I suppose,  either  that  the 
force  of  the  internal  vapour  which  impelled  the 
cloud  upwards  decreased  in  strength  as  it  ad- 
vanced, or  that  the  cloud,  being  pressed  back  by 
its  own  weight,  expanded  itself  in  the  manner  I 
have  mentioned : it  appeared  sometimes  bright, 
and  sometimes  dark  and  spotted,  as  it  was  either 
more  or  less  impregnated  with  earth  and  cinders. 
This  uncommon  appearance  excited  my  uncle’s 
philosophical  curiosity  to  take  a nearer  view  of  it. 
He  accordingly  ordered  a light  vessel  to  be  pre- 
pared, and  offered  me  the  liberty,  if  I thought 
proper,  to  attend  him.  I rather  chose  to  continue 
the  employment  in  which  I was  engaged ; for  it 
happened  that  he  had  given  me  a certain  writing 


ERUPTIONS  OF  VESUVIUS. 


33 


to  copy.  As  he  was  going  out  of‘  the  house  with 
his  tablets  in  his  hand,  he  was  met  by  the  mariners 
belonging  to  the  galleys  stationed  at  Retina,  from 
which  they  had  fled  in  the  utmost  terror ; for,  that 
port  being  situated  at  the  foot  of  Vesuvius,  they 
had  no  other  way  to  escape  than  by  sea.  They 
conjured  him,  therefore,  not  to  proceed,  and  ex- 
pose his  life  to  imminent  and  inevitable  danger. 
In  compliance  with  their  advice,  he  changed  his 
original  intention,  and,  instead  of  gratifying  his 
philosophical  spirit,  he  resigned  it  to  the  more 
magnanimous  principle  of  aiding  the  distressed. 
With  this  view,  he  ordered  the  fleet  immediately 
to  put  to  sea,  and  went  himself  on  board  with  an 
intention  of  assisting  not  only  Retina,  but  the 
several  other  towns  which  stood  thick  upon  that 
beautiful  coast.  Hastening  to  the  place,  there- 
fore, from  whence  others  fled  with  the  utmost 
terror,  he  steered  his  direct  course  to  the  point  of 
danger,  and  with  so  much  calmness  and  presence 
of  mind,  as  to  be  able  to  make  and  dictate  his 
observations  upon  the  appearance  and  progress  of 
that  dreadful  scene.  He  was  now  so  near  the 
mountain,  that  the  cinders,  which  grew  thicker 
and  hotter  the  more  he  advanced,  fell  into  the 
ships,  together  with  pumice-stones,  and  black 
pieces  of  burning  rock ; they  were,  likewise,  in 
danger  not  only  of  being  aground  by  the  sudden 


i)

ERUPTIONS  OF  VESUVIUS. 


retreat  of  the  sea,  but  also  from  the  vast  fragments 
which  rolled  down  from  the  mountains,  and  ob- 
structed all  the  shore.  Here  he  stopped  to  con- 
sider whether  he  should  return  back  ; to  which 
the  pilot  advising  him,  ‘ Fortune,’  said  he,  ‘ be- 
friends the  brave : steer  to  Pomponianus.’  Pom- 
ponianus  was  then  at  Stabia,  separated  by  a gulf 
which  the  sea,  after  several  insensible  windings, 
forms  upon  that  shore.  Pomponianus  had  already 
sent  his  baggage  on  board ; for,  though  he  was 
not,  at  that  time,  in  actual  danger,  yet,  being 
within  the  view  of  it,  and,  indeed,  extremely  near, 
he  was  determined,  if  it  should  in  the  least  increase, 
to  put  to  sea  as  soon  as  the  wind  should  change. 
It  was  favourable,  however,  for  carrying  my  uncle 
to  Pomponianus,  whom  he  found  in  the  greatest 
consternation  ; and,  embracing  him  with  tender- 
ness, he  encouraged  and  exhorted  him  to  keep  up 
his  spirits.  The  more  to  dissipate  his  fears,  he 
ordered  his  servants,  with  an  air  of  unconcern,  to 
carry  him  to  the  baths  ; and,  after  having  bathed, 
he  sat  down  to  supper  with  great,  or  at  least  (what 
is  equally  heroic)  with  all  the  appearance  of  cheer- 
fulness. In  the  mean  while  the  fire  from  Vesuvius 
flamed  forth  from  several  parts  of  the  mountain 
with  great  violence ; which  the  darkness  of  the 
nis;ht  contributed  to  render  still  more  visible  and 
dreadful.  But  my  uncle,  in  order  to  calm  the 


ERUPTIONS  OF  VESUVIUS. 


35 


apprehensions  of  his  friend,  assured  him  it  was 
only  the  conflagration  of  the  villages,  which  the 
country  people  had  abandoned.  After  this,  he 
retired  to  rest ; and  it  is  most  certain,  he  was  so 
little  discomposed  as  to  fall  into  a deep  sleep  ; for, 
being  corpulent,  and  breathing  hard,  the  attendants 
in  the  antechamber  actually  heard  him  snore. 

The  court  which  led  to  his  apartment  being  now 
almost  filled  with  stones  and  ashes,  it  would  have 
been  impossible  for  him,  if  he  had  continued  there 
any  longer,  to  have  made  his  way  out ; it  was 
thought  proper,  therefore,  to  awaken  him.  He 
got  up,  and  joined  Pomponianus  and  the  rest  of 
the  company,  who  had  not  been  sufficiently  un- 
concerned to  think  of  going  to  bed.  They  con- 
sulted together,  whether  it  would  be  most  prudent 
to  trust  to  the  houses,  which  now  shook  from  side 
to  side  with  frequent  and  violent  concussions,  or 
flee  to  the  open  fields,  where  the  calcined  stones 
and  cinders,  though  levigated,  indeed,  yet  fell  in 
large  showers,  and  threatened  them  with  instant 
destruction.  In  this  distress  they  resolved  for  the 
fields,  as  the  less  dangerous  situation  of  the  two ; 
a resolution  which,  while  the  rest  of  the  company 
were  hurried  into  by  their  fears,  my  uncle  em- 
braced, upon  cool  and  deliberate  consideration. 
They  went  out,  then,  having  pillows  tied  upon 
their  heads  with  napkins  ; and  this  was  their  whole

defence  against  the  storm  of  stones  that  fell  around 
them.  It  was  now  day  every  where  else,  but 
there  a deeper  darkness  prevailed  than  in  the 
blackest  night,  which,  however,  was  in  some  de- 
gree dissipated  by  torches  and  other  lights  of 
various  kinds.  They  thought  it  expedient  to  go 
down  farther  upon  the  shore,  in  order  to  observe  if 
they  might  safely  put  out  to  sea ; but  they  found 
the  waves  still  running  extremely  high  and  boister- 
ous. There  my  uncle,  having  drunk  a draught  or 
two  of  cold  water,  laid  himself  down  upon  a sail- 
cloth, which  was  spread  for  him ; when  immedi- 
ately the  flames,  preceded  by  a strong  smell  of 
sulphur,  dispersed  the  rest  of  the  company,  and 
obliged  him  to  rise.  He  raised  himself  up,  with 
the  assistance  of  two  of  his  servants,  and  instantly 
fell  down  dead ; suffocated,  I conjecture,  by  some 
gross  and  noxious  vapour,  as  having  always  had 
weak  lungs,  and  being  frequently  subject  to  a dif- 
ficulty of  breathing.  As  soon  as  it  was  light 
again,  which  was  not  till  the  third  day  after  this 
melancholy  accident,  his  body  was  found  entire,  and 
without  any  marks  of  violence,  exactly  in  the  same 
posture  in  which  he  fell,  and  looking  more  like  a man 
asleep  than  dead.  During  all  this  time,  my  mother

that,  therefore,  I will  put  an  end  to  my  letter. 
Suffer  me  only  to  add,  that  I have  faithfully  re- 
lated to  you  what  I was  either  an  eye-witness  of 
myselfj  or  received  immediately  after  the  accident 
happened,  and  before  there  was  time  to  vary  the 
truth.  You  will  choose  out  of  this  narrative  such 
circumstances  as  shall  be  most  suitable  to  your 
purpose ; for  there  is  a great  difference  between 
writing  a letter,  and  composing  a history  ; between 
addressing  a friend,  and  addressing  the  public. 
Farewell.” 

“ To  Cornelius  Tacitus.  * 

“ The  letter  which,  in  compliance  with  your  re- 
quest, I wrote  to  you,  concerning  the  death  of  my 
uncle,  has  raised,  it  seems,  your  curiosity  to  know 
what  terrors  and  dangers  attended  me  while  I con- 
tinued at  Misenum;  for  there,  I think,  the  account 
in  my  former  broke  off. 

* Though  my  shock’d  soul  recoils,  my  tongue  shall  tell.’ 

“ My  uncle  having  left  us,  I continued  the  em- 
ployment which  prevented  my  going  with  him,  till 
it  was  time  to  bathe ; after  which  I went  to  sup- 
per, and  then  fell  into  a short  and  unquiet  sleep. 
There  had  been,  during  many  days  before,  some 
shocks  of  an  earthquake,  which  the  less  alarmed 
us,  as  they  are  frequent  in  Campania;  but  they

were  so  particularly  violent  that  night,  that  they 
not  only  shook  every  thing  about  us,  but  seemed, 
indeed,  to  threaten  total  destruction.  My  mother 
Hew  to  my  chamber,  where  she  found  me  rising  in 
order  to  awaken  her.  We  went  out  into  a small 
court  belonging  to  the  house,  which  separated  the 
sea  from  the  buildings.  As  I was  at  that  time 
but  eighteen  years  of  age,  I know  not  whether  I 
should  call  my  behaviour,  in  this  perilous  conjunc- 
ture, courage  or  rashness ; but  I took  up  Livv, 
and  amused  myself  with  turning  over  that  author, 
and  even  making  extracts  from  him,  as  if  I had 
been  perfectly  at  my  ease.  While  we  were  in  this 
situation,  a friend  of  my  uncle’s,  who  was  just 
come  from  Spain,  to  pay  him  a visit,  joined  us, 
and  observing  me  sitting  by  my  mother  with  a 
book  in  my  hand,  reproved  her  patience  and  my 
security ; nevertheless  I still  went  on  with  my  au- 
thor. It  was  now  morning,  but  the  light  was 
exceedingly  faint  and  languid ; the  buildings  all 
around  us  tottered ; and  though  we  stood  upon 
open  ground,  yet,  as  the  place  was  narrow  and 
confined,  there  was  no  remaining  without  immi- 
nent danger : we  therefore  resolved  to  leave  the 
town.  The  people  followed  us  in  the  utmost  con- 
sternation, and  (as,  to  a mind  distracted  with  terror, 
every  suggestion  seems  more  prudent  than  its  own) 
pressed  in  great  crowds  about  us  in  our  way  out. 


ERUPTIONS  OF  VESUVIUS. 


Being  advanced  at  a convenient  distance  from 
the  houses,  we  stood  still,  in  the  midst  of  a most 
hazardous  and  tremendous  scene.  The  chariots, 
which  we  had  ordered  to  be  drawn  out,  were  so 
agitated  backwards  and  forwards,  though  upon 
the  most  level  ground,  that  we  could  not  keep 
them  steady  even  by  supporting  them  with  large 
stones.  The  sea  seemed  to  roll  back  upon  itself, 
and  to  be  driven  from  its  banks  by  the  convulsive 
motion  of  the  earth ; it  is  certain,  at  least,  the 
shore  was  considerably  enlarged,  and  several  sea- 
animals  were  left  upon  it.  On  the  other  side,  a 
black  and  dreadful  cloud,  bursting  with  an  ig- 
neous serpentine  vapour,  darted  out  a long  train 
of  fire,  resembling  flashes  of  lightning,  but  much 
larger.  Upon  this  our  Spanish  friend,  whom  I 
mentioned  above,  addressing  himself  to  my  mother 
and  me,  with  great  warmth  and  earnestness : ‘ If 
your  brother,  and  your  uncle,’  said  he,  ‘ is  safe, 
he  certainly  wishes  you  may  be  so  too ; but  if  he 
perished,  it  was  his  desire,  no  doubt,  that  you  might 
both  survive  him ; why,  therefore,  do  you  delay 
your  escape  a moment?’  We  could  never  think 
of  our  own  safety,  we  replied,  while  we  were  un- 
certain of  his  : upon  which  our  friend  left  us,  and 
withdrew  from  the  danger  with  the  utmost  preci- 
pitation. Soon  afterwards,  the  cloud  seemed  to 
descend,  and  cover  the  whole  ocean ; as,  indeed, 

d 4

it  entirely  hid  the  island  of  Caprea,  and  the  pro- 
montory of  Misenum.  My  mother  conjured  me 
to  make  my  escape  at  any  rate,  which,  as  I was 
young,  I might  easily  effect;  as  for  herself,  she 
said,  her  age  and  corpulency  rendered  all  attempts 
of  that  sort  impossible ; however,  she  would  will- 
ingly meet  death,  if  she  could  have  the  satisfaction 
of  seeing  that  she  was  not  the  occasion  of  mine. 
But  I absolutely  refused  to  leave  her ; and  taking 
her  by  the  hand,  I led  her  on  : she  complied  with 
great  reluctance,  and  not  without  many  reproaches 
to  herself  for  being  the  occasion  of  retarding  my 
flight.  The  ashes  now  began  to  fall  upon  us, 
though  in  no  great  quantity.  I turned  my  head, 
and  observed  behind  us  thick  smoke,  which  came 
rolling  after  us  like  a torrent ; 1 proposed,  while 
we  had  yet  any  light,  to  turn  out  of  the  high  road, 
lest  she  should  be  pressed  to  death  in  the  dark, 
by  the  crowd  that  followed  us.  We  had  scarcely 
stepped  out  of  the  path,  when  darkness  overspread 
us ; not  like  that  of  a cloudy  night,  or  when  there 
is  no  moon,  but  of  a room  when  it  is  shut  up,  and 
all  the  lights  extinct.  Nothing,  then,  was  to  be 
heard  but  the  shrieks  of  women,  the  screams  of 
children,  and  the  cries  of  men ; some  calling  for 
their  children,  others  for  their  parents,  others  for 
their  husbands,  and  only  distinguishing  each  other 
by  their  voices  ; one  lamenting  his  own  fate,  an-

other  that  of  his  family  ; some  wishing  to  die,  from 
the  very  fear  of  dying  ; some  lifting  their  hands 
to  the  gods ; but  the  greater  part  imagining  that 
the  last  and  eternal  night  was  come,  which  was 
to  destroy  both  the  gods  and  the  world  together. 
Among  these  there  were  some  who  augmented 
the  real  terrors  by  imaginary  ones,  and  made  the 
frighted  multitude  falsely  believe  that  Misenum 
was  actually  in  flames.  At  length  a glimmering 
light  appeared,  which  we  imagined  to  be  rather 
the  forerunner  of  an  approaching  burst  of  flames 
(as  in  fact  it  was),  than  the  return  of  day ; how- 
ever, the  fire  fell  at  a distance  from  us : then  again 
we  were  immersed  in  thick  darkness,  and  a heavy 
shower  of  ashes  rained  upon  us,  which  we  were 
obliged  every  now  and  then  to  shake  off  otherwise 
we  should  have  been  overwhelmed  and  buried  in 
the  heap.  I might  boast,  that  during  all  this  scene 
of  horror,  not  a sigh,  or  expression  of  fear,  escaped 
from  me,  had  not  my  support  been  founded  on 
that  miserable,  though  strong  consolation,  that  all 
mankind  were  involved  in  the  same  calamity,  and 
that  I imagined  I was  perishing  with  the  world  it- 
self. At  last,  this  terrible  darkness  was  dissipated 
by  degrees,  like  a cloud  or  smoke ; the  real  day 
returned,  and  even  the  sun  appeared,  though  very 
faintly,  and  as  when  an  eclipse  is  coming  on. 
Every  object  that  presented  itself  to  our  eyes

(which  were  extremely  weakened)  seemed  changed, 
being  covered  with  white  ashes,  as  with  a deep 
snow.  We  returned  to  Misenum,  where  we  re- 
freshed ourselves  as  we  could,  and  passed  an  anxi- 
ous night  between  hope  and  fear;  though,  indeed, 
with  a much  larger  share  of  the  latter  : for  the  earth 
still  continued  to  shake,  while  several  enthusiastic 
persons  ran  wildly  among  the  people,  throwing  out 
terrifying  predictions,  and  making  a kind  of  frantic 
sport  of  their  own  and  their  friends’  wretched  situ- 
ation. However,  my  mother  and  I,  notwithstand- 
ing the  danger  we  had  passed,  and  that  which 
still  threatened  us,  had  no  intention  of  leaving 
Misenum,  till  we  should  receive  some  account  of 
my  uncle. 

“ And  now,  you  will  read  this  narrative  without 
any  view  of'  inserting  it  in  your  history,  of  which 
it  is  by  no  means  worthy ; and,  indeed,  you  must 
impute  it  to  your  own  request,  if  it  should  appear 
not  to  deserve  even  the  trouble  of  a letter.  Fare- 
well.” 

Plutarch,  104  years  afterwards,  speaks  of  “ the 
eruption  of  fire  from  the  mountain,  the  agitation 
of  the  sea,  the  projection  of  rocks  and  flaming 
masses,  and  the  burying  of  many  cities,  at  present 
so  completely  lost  that  no  one  can  even  discern 
where  they  stood.”

Dion  Cassius*  gives  a description  of  this  erup- 
tion, but  lie  mixes  up  fact  with  the  tales  of  wonder 
which  had  been  invented  and  handed  down  by 
tradition  during  the  preceding  1,50  years.  He 
says,  “ Extraordinary  events  occurred  in  Campania, 
for  fire  suddenly  broke  out  from  Vesuvius,  in 
which  mountain  there  were  copious  sources  of  fire. 
Formerly  its  summit  was  equal  on  every  part,  the 
sides  untouched  by  fire,  and  the  interior  only, 
burnt  and  reduced  to  ashes.  A part  of  the  cir- 
cumference became  ignited,  was  consumed,  and 
fell,  leaving  the  rest  in  a concave  form,  so  that  it 
resembled  an  Amphitheatre.” 

After  describing  gigantic  apparitions  in  the  air, 
he  continues:  “A  great  dearth  followed,  and  violent 
earthquakes  shook  the  country.  Then  succeeded 
bellowing  noises,  both  subterranean  and  aerial; 
the  sea  roared  terribly,  and  sudden  crashes  were 
heard  as  if  mountains  were  rent  in  pieces.  Large 
stones  were  thrown  up,  and  great  masses  of  fire 
and  smoke,  so  that  the  air  was  darkened  and  the 
sun  obscured  as  if  eclipsed ; quantities  of  ashes 
covered  the  earth  and  sea,  destroying  every  thing, 
and  burying  two  entire  cities,  Herculaneum  and 
Pompeii,  while  the  people  sat  in  the  theatre ; the 
ashes  were  carried  to  Africa,  Syria,  and  Egypt,  and

great  terror  was  caused  in  Rome,  where  the  air 
was  so  completely  darkened  by  them  that  the  sun 
was  not  seen  for  a whole  day.” 

Galenus,  in  172  A.  D.,  describing  the  situation 
of  Vesuvius,  states  that  the  mountain  had  become 
celebrated  on  account  of  the  eruption. 

Eutropius*,  who  wrote  A.D.  370,  in  detailing  the 
events  of  the  reign  of  Titus,  says,  “ At  that  time, 
also,  Vesuvius,  a mountain  of  Campania,  opened; 
there  came  out  a quantity  of  burning  matter ; and 
the  neighbouring  region,  with  its  cities  and  in- 
habitants, was  destroyed  by  floods  of  flame.” 

203  A.  D.  The  second  eruption  is  also  alluded 
to  by  Dion  in  the  life  of  Septimius  Severus.t 
“ In  those  days,”  says  he,  “ an  immense  fire  broke 
out  on  the  mountain  Vesuvius;  and  such  was  the 
loudness  of  the  explosions,  that  they  were  heard 
even  at  Capua,  in  which  city  I reside  when  I 
make  any  stay  in  Italy.” 

472  A.  D.  Sigonius,  in  his  history  of  the  West- 
ern Empire!,  speaks  of  the  third  eruption  as 
follows : “ In  the  year  472,  Vesuvius,  a mountain  of 
Campania,  disturbed  by  internal  fire,  vomited  out 
its  burnt-up  entrails ; a darkness,  like  that  of  night, 
reigned  during  the  day,  and  all  Europe  was  covered 
with  fine  ashes.”  According  to  his  account  the

latter  fell  in  Constantinople,  where  they  raised 
considerable  curiosity,  and  even  created  some 
alarm. 

512  A.  D.  The  fourth  eruption  happened  dur- 
ing the  reign  of  Theodoric;  and  Cassiodorus,  in  a 
letter  to  the  king,  describes  it  as  having  com- 
menced with  a violent  rumbling  sound  in  the 
interior  of  the  mountain,  then  columns  of  thick 
smoke  and  ashes  were  thrown  out,  the  latter  falling 
at  great  distances  from  the  mountain  ; streams  of 
hot  sand  glided  down  from  its  summit ; and  the 
sides  of  these  torrents,  impeded  in  their  course, 
were  heaped  up,  forming  two  banks  between  which 
the  sand  flowed  like  water. 

085  A.  D.  In  the  month  of  March  and  in  the 
reign  of  Constantine  the  Fourth,  the  next  eruption 
occurred,  in  which  much  fire  was  seen  on  the 
summit  and  a great  quantity  of  ashes  ejected. 

993  A.  D.  The  sixth  eruption  now  took  place, 
and  Glabrus  Rodolphus,  according  to  Baronius, 
relates  “ that  there  happened  very  wonderful 
eruptions  of  fire  from  Vesuvius.  Besides  the 
injury  done  to  many  other  cities  of  Italy,  Rome 
was  burnt  in  several  parts,  the  fire  attacking  the 
cathedral  of  St.  Peter.  Prayers  were  offered  up  to 
the  Apostle  to  implore  his  aid  for  the  preservation 
of  the  buildings,  and  we  are  told  that  the  fire 
immediately  ceased.”  It  is  supposed  that  this  is 


46

also  the  eruption  which  Guaimarius  prince  of  Sa- 
lerno is  said  to  have  seen,  when  “ from  afar  off  he 
beheld  the  pitchy  and  sulphurous  flames  that  burst 
suddenly  from  Vesuvius.” 

1086  A.  D.  The  seventh  eruption  began  on  the 
27th  February,  and  is  the  first  in  which  any  mention 
is  made  of  lava,  or  of  liquefied  matter,  that  in  cool- 
ing became  hard  and  of  the  consistence  of  stone. 
The  lava  not  only  flowed  from  the  summit,  but 
also  from  the  sides  of  the  cone,  and  ran  down  into 
the  sea. 

1049  A.  D.  The  eighth  eruption  is  supposed 
to  have  been  remarkable  for  the  quantity  of  lava  it 
threw  out,  which  is  described  in  the  account  that 
Marsicano,  cardinal  and  bishop  of  Ostia,  has  given 
of  it  as  “ a torrent  of  sulphurous  resin  or  bitumen, 
that  descended  to  the  sea  and  became  petrified.” 

1138  A.  D.  The  ninth  eruption  occurred  on 
the  29th  May,  and  the  anonymous  writer  in  the 
Chronicles  of  the  Convent  of  Monte  Casino,  says, 
“ the  mountain  Vesuvius  threw  out  fire  for  forty 
days;”  and  he  again  alludes  to  it  in  speaking  of 
the  coming  of  Roger  the  Third  to  Salerno  : “ After 
this  there  was  a great  eruption  of  Vesuvius, 
followed  by  heavy  clouds  of  dust  that  darkened 
the  air  and  covered  the  whole  region  even  to  the 
Principato  Ultra  and  Calabria,  their  motion  increas- 
ing and  decreasing,  as  if  agitated  by  the  wind.” 


ERUPTIONS  OF  VESUVIUS. 


47 


1139  A.  D.  The  tenth  eruption  was  accompa- 
nied by  a great  quantity  of  fire,  which  lasted  eight 
days ; and  for  thirty  days  after,  dark  and  alarming 
clouds  of  ashes  were  ejected. 

1306  A.  D.  During  the  eleventh  eruption  a 
torrent  of  melted  matter  flowed  down  to  the  sea, 
laying  waste  a great  extent  of  country. 

1500  A.  D.  The  twelfth  eruption  was  witnessed 
by  Leon  of  Nola,  who  wrote  a description  of  his 
native  place  and  of  Vesuvius.  Among  the  sub- 
stances thrown  out  he  notices  showers  of  red  ashes, 
which  fell  over  a great  space  of  country  around 
Vesuvius. 

The  long  interval  of  repose  between  the  twelfth 
and  thirteenth  eruptions*  enabled  the  proprietors  of 
land  on  the  mountain  to  cultivate  it  higher  up 
towards  the  cone ; and  we  are  told  that  all  the 
plain  (now  the  Atrio  and  Pedementina)  around 


* A.  D.  1538.  During  the  years  1537  and  1538  numerous 
shocks  of  earthquakes  were  felt  along  the  whole  coast  of  Baia, 
and  on  the  27th  and  28th  September  in  the  latter  year,  they  be- 
came violent  and  terrifying.  About  8 o’clock  in  the  evening  of 
the  29th  a fissure  opened  in  the  earth  near  Tripergola,  a village 
famous  for  its  baths,  situated  about  a mile  to  the  west  of  Pozzuoli. 
A conical  shaped  hill,  formed  of  the  matter  extruded  during  that 
night  and  the  following  day,  rose  up  through  the  chasm,  de- 
stroying and  occupying  the  site  of  the  village,  as  well  as  the 
greater  part  of  the  Lucrine  lake.  Its  present  height  is  440 
English  feet  above  the  level  of  the  sea ; and  the  depth  of  its 
crater,  which  is  an  inverted  cone,  is  421  feet,  and  it  is,  at  its 
base,  nearly  a mile  and  a half  in  circumference. 


1.8

it  was  covered  with  herbage  fit  for  cattle,  and 
many  plants  very  useful  for  medical  purposes. 

The  base  of  the  cone  was  six  miles  round,  and 
its  steep,  barren  sides  rose  350  geometrical  feet 
above  the  plain.  From  its  summit  was  visible 
a gulf  a thousand  paces  deep,  four  miles  in 
circuit,  and  shaped  like  the  hull  of  a ship : it  was 
surrounded  by  a skreen  of  burnt  rock  on  which 
nothing  would  grow  ; but  a slope  descended  thence 
to  a narrow  ledge  covered  with  shrubs,  where  a 
zigzag  path  went  through  thickets  to  a plain  at 
the  bottom,  and  there  cattle  might  graze,  for  the 
vegetation  flourished  wherever  the  sun  reached  it. 

Oaks,  elms,  holm-oaks,  lime  and  ash  trees, 
besides  privet,  broom,  and  other  shrubs,  covered 
one  part  of  the  plain,  and  among  them  wild  boars 
frequently  took  shelter ; in  another  part  there 
were  three  pools,  the  water  of  one  of  which  was 
hot  and  bitter,  of  another  hot  and  tasteless,  and 
that  of  the  third  was  salter  than  the  sea;  while 
the  plain  towards  the  South  East  was  distinguished 
only  by  being  strewn  with  ashes. 

1631  A.  D.  The  thirteenth  eruption  was  pre- 
ceded by  shocks  of  earthquakes,  and  the  drying 
up  of  the  wells  around  the  mountain.  On  the 
1 6th  of  December  the  volcano  threw  out  immense 
volumes  of  smoke,  which  rose  in  the  shape  of  a 
pine-tree,  in  the  manner  described  by  Pliny,  and 


ERUPTIONS  OF  VESUVIUS.

thence  spreading  out,  cast  a shade  over  the  whole 
gulf,  and  covered  the  country  with  ashes  and  sand. 
In  the  midst  of  the  thick  smoke,  “ vivid  flashes  of 
lightning,  like  arrows  of  fire,  were  frequently  seen  ; 
thunder  was  heard  to  roll  fearfully,  and  vast  stones 
were  shot  from  the  crater.”  The  next  day  a part 
of  the  western  side  of  the  crater  burst  open,  and  a 
sulphurous,  bituminous,  vitrified  matter  rapidly 
descended  the  mountain  like  a torrent  of  molten 
glass,  and  a stream  of  hot  ashes  ran  from  the 
summit,  laying  waste  the  country.  The  torrent  of 
lava  divided  itself  into  seven  principal  streams, 
destroying  gardens,  vineyards,  towns,  every  thing 
that  lay  in  its  way.  One  stream  ran  to  Pietra 
Bianca,  between  Sta.  Maria  di  Securreris  near  Por- 
tici ; the  third  to  St.  Giorgio  and  Cremano  in 
St.  Iorio,  which,  except  the  church,  was  totally 
destroyed.  A fourth  reached  Portici  and  Grana- 
tello ; a fifth  Resina,  completely  overwhelming  it 
and  Torre  del  Greco,  of  which  two  thirds  were 
laid  in  ruins.  The  sixth  went  to  Torre  dell’ 
Annunziata,  which  it  nearly  destroyed,  and  the 
seventh  to  Massa,  St.  Sebastiano,  and  la  Madonna 
dell’  Arco : four  thousand  people  fell  victims  to 
the  flames,  and  the  whole  country  presented  one 
heap  of  smoking  ruins. 

After  the  eruption  it  rained  heavily  for  two 
days ; and  the  water  rushing  down  the  sides  of  the 

E

mountain,  carried  sand  and  ashes  along  with  it, 
laying  waste  the  land  which  had  not  been  touched 
by  the  lava,  and  even  covering  houses  in  its  course. 
On  the  20th  an  earthquake  shook  the  mountain, 
and  was  felt  in  Naples,  where  it  alarmed  the 
people,  and  did  considerable  damage.  On  the 
28th  a torrent  of  water  a«;ain  flowed  down  the 
mountain,  and,  as  there  had  been  no  rain  for 
several  days,  many  supposed  that  it  was  water 
sucked  from  the  sea  into  the  hollow  under  Vesuvius 
and  again  forced  out  from  its  mouth  : some  people 
declared  that  they  had  found  sea-weed  in  it  and 
fish  ready  boiled.  It  is  possible,  that  the  water, 
from  the  rains,  had  been  pent  up  in  the  valley 
between  Somma  and  the  cone  by  ashes ; and  had, 
at  last,  burst  its  barrier.  Rumbling  sounds  in  the 
mountain  were  heard  for  many  days,  and  then  it 
became  perfectly  tranquil. 

1660  A.D.  The  fourteenth  eruption  occurred 
in  the  month  of  July,  unaccompanied  by  any 
noise.  The  lava  boiled  up  within  the  crater  until 
it  reached  the  summit,  and  then,  flowing  over,  ran 
down  on  the  country.  This  was  succeeded  by 
great  quantities  of  smoke,  charged  with  dust  and 
ashes,  which  fell  and  did  much  damage  to  the 
vineyards. 

1682  A.D.  The  fifteenth  eruption  happened  on 
the  12th  August.  The  smoke  issued  from  the

summit  in  the  shape  of  a pine,  and  showers  of 
ashes  and  lapillo  followed.  The  smoke  was  con- 
stantly evolved  till  the  22d,  accompanied  by  light- 
ning, which  flashed  through  it,  and  by  some 
inconsiderable  earthquakes.  The  level  of  the  lava 
in  the  crater  was  considerably  raised,  but  it  did 
not  overflow.  Slight  eruptions  also  occurred  during 
the  years  1685  and  1689- 
1694*  A.  D.  The  mountain  remained  tranquil 
until  the  12th  of  March,  when  the  16th  eruption 
took  place.  A great  earthquake,  early  in  the 
month,  had  prepared  the  inhabitants  for  an  ex- 
plosion, which  in  fact  happened  at  nine  o’clock  in 
the  evening.  The  lava  flowed  over  the  summit 
and  ran  towards  the  Fosso  Corvo,  where  it  sepa- 
rated into  two  streams,  one  of  which  slowly  ap- 
proached Torre  del  Greco,  the  other  St.  Iorio. 
Two  years  afterwards  another  stream  issued  from 
the  summit  taking  the  direction  of  the  Hermitage, 
till  its  progress  was  arrested  by  the  lava  of  1694. 
Again,  on  the  15th  and  16th  September,  1697>  a 
stream  flowed  towards  Torre  del  Greco,  over  the 
old  one,  much  alarming  the  inhabitants  of  the 
town.  On  the  25th  May,  16Q8,  the  lava  once  more 
rushed  down,  and,  separating  into  two  streams, 
took  its  way  to  the  Hermitage  and  Resina.  Soon 
after  another  stream  directed  itself  towards  Torre 
del  Greco  and,  in  two  days,  had  very  nearly 


e 2

approached  it.  Much  smoke  and  dust  were  thrown 
out,  accompanied  by  loud  detonations  ; but  by  the 
12th  of  June  the  mountain  had  become  tranquil. 

1701  A.  D.  The  seventeenth  burst  out  on  the 
1st  of  July  with  showers  of  stones  and  ashes;  the 
next  day  the  lava  flowed  from  tiie  summit  towards 
the  woods  of  Ottajano  and  Bosco  Reale.  On 
the  15th  the  mountain  was  quiet,  and  the  lava  had 
stopped. 

1704  A.  D.  On  the  20t,h  of  May,  the  eighteenth 
eruption  commenced  by  a shower  of  ashes,  accom- 
panied by  a hollow  rumbling  sound,  which  was 
heard  at  a great  distance.  The  lava  rose  above 
the  edge  of  the  crater,  but  did  not  pass  it.  In 
1705,  1706,  and  from  the  28th  July  to  the  18th  of 
August,  1707,  and  on  the  14th  of  August,  170S,  the 
same  phenomena  occurred. 

1712  A.D.  The  nineteenth  eruption  began  on 
the  15th  February,  but  it  was  not  until  the  26th  of 
April  that  the  lava  appeared  on  the  outside  of  the 
cone,  when  a considerable  stream  descended  its 
southern  flank  towards  the  Fosso  Bianco.  Several 
smaller  streams  flowed  into  the  territory  around 
Torre  del  Greco  on  the  12th  and  17th  of  May 
following.  On  the  29th  of  October  a new  stream 
reached  the  Fosso  Bianco,  and  advanced,  on  the 
8th  November,  towards  Torre  del  Greco.  In  May, 
1713,  the  lava  again  issued  from  the  summit, 


ERUPTIONS  OF  VESUVIUS. 


53 


directing  itself,  at  different  times,  towards  Ottajano, 
Torre  del  Greco,  Resina;  and  in  June,  1714,  it 
flowed  towards  Torre  dell’  Annunziata,  for  several 
days,  accompanied  by  showers  of  ashes  and  sub- 
terranean detonations. 

1717  A.D.  The  twentieth  eruption  occurred  on 
the  6th  June.  The  southern  side  of  the  cone  burst 
open,  and  the  lava  rushed  out,  flowing  in  two 
directions,  one  being  Bosco  Tre  Case,  and  the 
other  lying  between  the  Camaldoli  and  Torre  del 
Greco:  on  the  16th  September,  1718,  more  lava 
issued,  one  part  flowing  towards  Mauro,  and  another 
to  Bosco  Reale  and  Resina.  Vesuvius  continued 
in  a state  of  occasional  activity  till  July,  1719,  when 
it  became  tranquil.  In  1723  the  lava  spread  out 
like  a lake,  in  the  valley  between  Somma  and  the 
cone,  and,  on  the  29th  of  June,  descended  towards 
Mauro : it  continued  to  do  so  till  the  8th  of  July. 
In  1724  and  172.5  the  lava  flowed  over  that  of  the 
preceding  years,  but  on  the  20th  April,  1726,  it  ran 
towards  the  Hermitage  and  Torre  del  Greco.  In 
March,  1727,  and  July,  1728,  other  lavas  flowed 
over  these. 

1730  A.D.  The  twenty-first  eruption  began 
on  the  27th  February,  announced  by  a shower  of 
ashes  and  dust,  which  was  thrown  out  with  a dread- 
ful noise.  In  eleven  days  from  the  19th  March  a 
torrent  of  lava  descended  into  the  woods  of  Otta- 


e 3

jano.  In  1732  the  lava  flowed  out,  on  the  8th 
January,  and  continued  running,  at  long  intervals, 
till  the  1st  of  May.  In  June,  Sorrentini  says,  the 
level  of  the  lava  was  even  with  the  edge  of  the 
crater,  and  on  the  10th  July  it  ran  over  and  flowed 
down  the  mountain,  at  several  times,  until  the 
middle  of  January,  1734,  when  it  became  quiet. 

1737  A.D.  The  twenty-second  eruption  was 
preceded  by  an  enormous  column  of  smoke,  which 
rose  from  the  crater  on  the  14th  of  May.  On  the 
15th  and  16th  the  lava  was  higher  than  the  edge 
of  the  crater,  and  it  flowed  over,  menacing  Bosco 
lleale  with  destruction ; at  the  same  time,  very 
large  stones  were  continually  shot  up,  from  the 
centre  of  the  crater.  On  the  20th  the  showers  of 
ashes  and  lapillo  were  immense,  and  rumblings 
were  heard  in  the  mountain.  At  six  in  the  even- 
ing an  opening  was  formed  in  the  southern  side, 
through  which  a quantity  of  lava  issued,  and  de- 
scended, in  four  hours,  to  the  outer  edge  of  the 
plain  of  the  Pedementina.  At  one  in  the  morning 
of  the  21st  the  stream  of  lava  had  greatly  aug- 
mented; and,  splitting  at  the  base  of  the  cone  into 
several  streams,  it  proceeded  towards  Resina, 
filling  up  a deep  ravine,  covering  a great  extent  of 
land  around  Torre  del  Greco,  and,  reaching  the 
sea  on  the  same  day,  ceased  to  flow.  Volumes  of 
smoke,  ashes,  and  lapillo  were  vomited  out  of  the

crater  during  the  eruption  : flashes  of  fire  con- 
stantly darted  through  the  smoke,  and  were  called 
by  the  common  people  “ ferilli.” 

1751  A.D.  The  twenty-third  eruption  hap- 
pened in  October,  on  the  22d  of  which  month,  at 
five  o’clock  in  the  morning,  violent  explosions 
were  heard  on  the  side  of'  the  crater  towards  Bosco 
Reale.  On  the  23d  an  earthquake  was  felt  at 
Massa,  and  also  at  Naples;  and  on  the  25th,  about 
midnight,  the  cone,  a little  above  its  base  and 
opposite  Bosco  Tre  Case,  burst  open,  a stratum  of 
compact  ancient  lava,  partly  melted  by  the  heat, 
having  been  turned  over.  A stream  issued  im- 
mediately, descended  to  the  plain,  and  flowed 
towards  Tre  Case ; but  lower  down  it  changed  its 
course,  and  running  on  to  Mauro,  traversed  a dis- 
tance of  four  miles  in  eight  hours,  burning  up 
every  thing  with  which  it  came  in  contact.  In 
November  it  had  ceased  to  run,  but  it  was  many 
months  in  cooling.  Two  smaller  streams  went 
towards  the  Bosco  d’  Ottajano,  but  soon  stopped. 

1754  A.D.  The  twenty-fourth  eruption  broke 
out  abruptly  on  the  2d  of  December : the  cone 
presented  two  openings,  one  facing  Bosco  Tre 
Case,  and  the  other  over  Ottajano:  the  lava  from 
them  advanced  towards  both  of  these  places. 
Della  Torre  observed  in  the  air,  close  to  the  column

those  occasioned  by  the  discharge  of  cannon;  and 
they  remained  in  the  air  from  15  to  23  minutes, 
till,  at  length,  they  were  dissipated  by  the  wind. 
This  fact  had  been  noticed  in  1730  by  Sorrentini. 
About  the  end  of  the  following  January  an  in- 
terior or  small  cone  was  seen,  from  Naples,  above 
the  edge  of  the  great  crater;  and  on  the  31st  the 
great  cone  burst  open  opposite  the  eastern  end  of 
Somma,  and  lava  flowed  out  for  two  months, 
following  the  course  of  a former  stream  towards 
the  woods  of  Ottajano.  The  mountain  continued 
in  a state  of  almost  uninterrupted  activity  from 
1754  to  1759. 

1759  A.D.  The  twenty-fifth  eruption  occurred 
on  the  27th  of  March.  On  the  29th  the  explosions 
were  awful,  and  shook  the  windows  in  Naples. 
On  the  30th,  at  seven  o’clock  in  the  evening,  the 
lava  issued  from  the  summit,  and  flowed  with  great 
rapidity  down  the  mountain ; and,  though  it  ceased 
the  next  day,  it  did  much  injury  to  property. 

1 760  A.  D.  The  twenty-sixth  eruption  was  re- 
markable for  the  situation  of  the  opening,  whence 
the  lava  flowed.  It  was  not,  as  it  had  always 
been  before,  on  the  side  of  the  cone,  or  on  the 
plain  near  its  base,  but  at  a great  distance  down 
on  its  southern  flank,  about  one  mile  above  the 
convent  of  the  Camaldoli  della  Torre.  After  se- 
veral shocks  of  earthquake,  and  great  fermentation 


ERUPTIONS  or  VESUVIUS.  57 

in  the  interior  of  the  mountain,  twelve  openings 
were  there  formed  with  a fearful  uproar,  which 
lasted  a considerable  time,  and  resembled  a con- 
tinual discharge  of  heavy  artillery.  From  these 
openings  quantities  of  small  red-hot  stones  were 
ejected,  accompanied  by  black  smoke  which  rose 
like  a great  pine,  a shape  very  common  in  great 
eruptions.  Lava  then  flowed  from  them  towards 
the  high  road  between  Naples  and  Torre  dell’ 
Amiunziata.  On  the  23d,  in  the  evening,  three 
new  openings  were  formed,  and  the  lava  next  day 
arrived  at  the  road.  On  the  26th  a new  stream 
took  the  direction  of  Bosco  Tre  Case,  and.  great 
volumes  of  smoke  ascended  from  the  crater.  On 
the  28th  a current  of  lava  took  its  course  towards 
Torre  del  Greco,  but  it  stopped  on  the  29th. 
The  progress  of  these  streams  was  slow,  and  the 
principal  one  did  not  reach  the  sea,  though  it  ap- 
proached to  within  twelve  paces  of  it.  The  ejection 
of  smoke  and  stones  from  the  crater  did  not  stop 
till  the  7th  January,  1761,  when  the  noise,  which 
had  continued  till  then,  ceased  and  no  smoke  ap- 
peared, either  from  the  crater  or  from  the  openings 
whence  the  lava  had  risen. 

Over  these  openings  three  truncated  conical 
craters,  which  still  exist,  were  thrown  up,  and  now 
bear  the  name  of  Vocoli  or  Viuli.  The  upper 
edge  of  the  smallest  has  a circumference  of  more

than  a hundred  feet ; the  interior  cavity  is  forty 
feet  deep.  Small  trees  and  brushwood  grow 
within  them,  and  the  outsides  of  two  of  them  are 
planted  with  vines. 

1766  A.D.  The  twenty-seventh  eruption  oc- 
curred after  four  years  of  complete  repose,  the 
white  smoke  which  occasionally  escaped  from  the 
crater  being  the  only  sign  that  it  had  not  become 
extinct.  On  the  28th  of  March  dense  smoke 
escaped  from  the  mountain,  burning  stones  were 
ejected ; and  the  side  of  the  cone,  towards  Resina, 
burst  open  near  the  summit,  considerably  diminish- 
ing its  height  on  that  side,  and  the  lava  flowed 
down  to  the  Atrio  del  Cavallo.  On  the  6th  of  April 
the  small  interior  cone  could  be  seen  from  Naples, 
and  on  the  10th  the  opposite,  or  s.  e.  side,  was  rent ; 
and  lava,  issuing  occasionally,  ran  towards  the 
Bosco  d’Ottajano  until  the  December  following. 

1767  A.D.  The  twenty-eighth  eruption  oc- 
curred in  March : the  small  cone  in  the  interior  of 
the  great  crater  was  seen  from  Naples,  above  the 
edge  of  the  great  one  ; and  at  night  large  masses  of 
molten  lava  that  were  thrown  out  were  plainly 
discernible.  During  the  summer,  lava  descended 
from  the  inner  cone  and  filled  the  bosom  of  the 
greater  one  ; and  from  September  until  the  19th 
of  October  the  projection  of  stones  became  more 
violent.  On  that  day  the  noise  was  so  loud  as  to 


ERUPTIONS  OF  VESUVIUS. 


59 


be  distinctly  heard  at  Naples;  and  the  smoke  rose  in 
dense  masses,  piled  upon  each  other  like  heavy 
thunder  clouds,  and  hung  over  the  gulf  from 
Casteir  Amare  to  Ischia.  Towards  the  close  of 
the  day  the  mountain  opened  near  the  summit,  on 
the  side  towards  Bosco  Reale,  and  a torrent  of 
lava  flowed  down  to  the  Pedementina,  whence  one 
branch  went  towards  Resina,  the  other  to  Ottajano. 
The  concussions  from  the  explosions  made  the 
windows  in  Naples  rattle,  and  greatly  frightened 
the  people  ; but  next  day  their  terror  was  increased, 
by  the  smoke  becoming  so  thick,  and  falling  so  low, 
that  Vesuvius  could  not  be  seen.  In  the  evening, 
just  as  the  shade  of  night  began  to  add  to  the 
obscurity  caused  by  this  mist  of  ashes,  an  awful 
crash  appalled  even  the  bravest,  for  all  were 
ignorant  from  what  it  had  proceeded.  The  follow- 
ing morning  it  was  discovered  that  the  cone  had 
been  split  from  the  summit,  to  more  than  half  way 
down,  and  that  lava  had  flowed  out  over  the  Atrio 
and  far  into  the  vineyards  near  St.  Jorio.  On  the 
23d  the  volcano  became  more  tranquil : on  the 
24th  fine  sand  fell  in  Naples,  and  ashes  near  the 
mountain ; but  on  the  27th  it  was  once  more 
tranquil. 

1771  A.  D.  On  the  first  of  May  the  twenty- 
ninth  eruption  began,  by  a rumbling  hoarse  sound 
in  the  interior  of  the  mountain ; and,  at  mid-day, 


()0  ERUPTIONS  OF  VESUVIUS. 

the  Java  issued  from  a crack  in  the  cone,  about 
two  hundred  feet  below  its  summit.  On  the  9th 
it  again  flowed  from  the  same  opening,  but  with 
greater  rapidity  than  before,  in  a winding  course, 
over  the  Atrio  del  Cavallo ; and,  entering  into  the 
cultivated  parts,  it  did  much  damage. 

1779  A.  D.  The  thirtieth  eruption  occurred  at 
about  seven  in  the  evening,  on  the  8th  of  August. 
An  immense  cloud  of  black  smoke,  loaded  with 
ashes,  rose  from  the  mountain,  and  showers  of 
ignited  masses  were  thrown  out  on  the  flanks  of 
Vesuvius,  in  such  quantities,  that,  at  night,  its 
black  form  seemed  as  if  studded  with  millions  of 
stars.  Lava,  also,  ran  from  the  summit  of  the  cone 
for  a short  distance,  but  ceased  in  a few  days. 

17S6  A.D.  The  thirty-first  eruption  began  in 
November,  1785,  when  several  small  craters  broke 
out  on  the  side  of  the  cone  towards  Somma.  In 
January,  I7S6,  the  eruption  greatly  increased,  and 
the  lava,  issuing  from  a rent  near  the  smaller  crater, 
flowed  into  the  Fosso  Vetrana,  where,  at  the 
commencement  of  the  ravine,  it  fell  over  a per- 
pendicular precipice,  forming  a beautiful  cataract, 
and  proceeding  thence,  reached  the  little  chapel  of 
the  Madonna  della  Vetrana,  forced  a passage 
through  it,  the  side  walls,  which  it  left  uninjured, 
serving  as  sides  to  its  extraordinary  channel ; and

after  running  several  hundred  yards  further  down 
the  Fosso,  it  stopped. 

1790  A.  D.  The  thirty-second  eruption  hap- 
pened in  the  month  of  September.  A great  quan- 
tity of  lava  was  moving  about  within  the  crater, 
which  it  almost  filled  to  the  brim.  For  many 
days,  stones  in  great  masses,  and  smoke,  were 
thrown  out  from  a small  crater  in  the  interior. 
Two  streams  of  lava  at  last  issued  and  took  a 
southerly  direction,  but,  towards  the  end  of  Oc- 
tober, the  mountain  became  quiet. 

1794  A.D.  The  thirty-third  eruption  was  a 
memorable  one,  and  occurred  on  the  15th  June. 
For  several  days  before  it  happened  the  water 
disappeared  from  the  wells  in  the  neighbourhood 
of  the  mountain ; and,  in  the  evening  of  the  12th 
at  10  o’clock,  the  shock  of  an  earthquake,  which 
undulated  from  east  to  west,  was  felt  in  the 
country  around  Naples.  A second  occurred  at  two, 
and  a third  at  eight,  in  the  morning  of  the  1 3th.  A 
very  smart  shock  took  place  in  the  evening  of  the 
15th  ; and  immediately  afterwards  the  mountain 
burst  open,  about  midway  between  the  centre  of 
the  Piano  delle  Ginestre  and  the  base  of  the  cone, 
on  the  s.  s.  w.  side,  between  Resina  and  Torre  del 
Greco.  Lava  in  great  quantities  instantly  boiled 
out,  with  a noise  like  the  discharge  of  heavy  guns, 
and  rolled  down  the  mountain  in  copious  weaves, 


ERUPTIONS  OF  VESUVIUS.

with  great  velocity,  towards  Resina,  but  suddenly 
turned  and  rushed  upon  Torre  del  Greco,  over- 
whelming four  fifths  of  the  town,  and  flowing  650 
feet  into  the  sea,  having  passed  a distance  of  6000 
yards,  in  the  short  space  of  eight  hours.  On  the  19th 
a discharge  of  ashes,  greater  than  had  yet  occurred, 
took  place ; a portion  of  the  southern  and  western 
edge  of  the  crater  having  fallen  in  during  the 
preceding  night,  lowering  the  summit  of  the 
mountain,  in  that  part,  about  a ninth  of  its  whole 
height  above  the  sea.  Quantities  of  ashes  fell  in 
Naples  and  the  neighbourhood.  On  the  8th  July 
all  appearance  of  eruption  had  ceased. 

Breislak  gives  the  following  description  of  the 
interior  of  the  crater  on  the  12th  July : — “ To  the 
eye  the  circumference  appeared  to  be  two  miles, 
but,  when  measured,  it  proved  to  be  only  one  mile 
and  a quarter.  The  part  towards  the  n.  e.  was 
the  highest  and  the  s.  w.  the  lowest,  so  that  the 
cone  appeared  truncated  by  a section  inclining  to 
that  side : the  form  of  the  circumference  was  an 
ellipsis  slightly  eccentric,  so  that  it  might  be  con- 
sidered almost  as  circular.  The  edge  was  not 
even,  and  did  not  decline  uniformly,  on  the  one 
side,  from  n.  e.  to  s.  w.,  nor  rise  equally,  on  the 
other,  from  s.  w.to  n.  e.,  but  formed  alternate  risings 
and  hollows,  the  deepest  of  them  lying  on  the 
south,  which  was,  therefore,  the  lowest  part  of  the 


ERUPTIONS  OF  VESUVIUS. 


63 


edge  of  the  crater.  The  height  of  the  cone  was 
740  feet,  and  the  depth  of  the  abyss  of  the  crater 
500.  The  sides  of  the  crater  had  a rapid  declivity, 
those  of  the  northern  or  highest  point  being  almost 
perpendicular.  The  bottom  was  a sort  of  plain  or 
valley,  running  east  and  west,  as  the  northern  and 
southern  sides  of  the  crater  narrowed  it,  by  jutting 
corners  or  abutments.” 

1804  A.D.  The  thirty- fourth  eruption  took 
place  on  the  12th  of  August,  unaccompanied  by 
earthquakes.  Smoke  and  lava  were  thrown  out 
from  the  crater,  but  without  any  noise.  The 
latter,  however,  flowed  from  the  summit,  down 
towards  the  convent  of  the  Camaldoli,  and  laid 
waste  a great  extent  of  country. 

1805  A.D.  The  thirty-fifth  eruption  was  of 
short  duration,  but  the  interior  crater  continued  to 
cast  out  ashes  and  smoke  throughout  the  year. 
The  lava  issued  from  the  s.  e.  summit,  and  flowed 
towards  Torre  del  Greco,  threatening  devastation, 
similar  to  that  of  1794,  but  stopped  within  a short 
distance  of  the  palace  of  the  Cardinal,  on  the 
eastern  side  of  the  town. 

1806  A.D.  On  the  3 1st  of  May,  about  seven 
in  the  evening,  the  thirty-sixth  eruption  began  ; 
and  a great  deal  of  tire  was  seen  to  issue  from  the 
mouth  of  the  small  crater,  with  dense  smoke,  and 
a jet  of  large  masses  of  melted  matter.  The  lava 


64 


ERUPTIONS  OF  VESUVIUS. 


then  began  to  flow  from  the  summit,  following  the 
course  of  former  streams,  towards  the  convent  of 
the  Camaldoli  and  Torre  del  Greco.  Lapillo 
fell,  in  considerable  quantities,  at  Ottajano,  and 
ashes  at  Nola.  On  the  5th,  6th,  and  7th  of  June, 
showers  of  ashes  were  thrown  out  towards  the  sea, 
and  after  this  the  eruption  ceased. 

1810  A.D.  The  thirty-seventh  eruption  oc- 
curred on  the  11th  of  September,  when  tremendous 
noises  burst  from  the  mountain,  and  lava  and  ashes 
were  shot  from  its  summit.  On  the  12th  the 
noises  increased,  as  also  the  ejection  of  ashes.  On 
the  13th  the  lava,  from  several  openings  near  the 
summit,  took  a direction  towards  Bosco  Tre  Case, 
Ottajano,  and  Resina ; but  though  this  lasted  for 
some  days,  very  little  injury  was  done  to  the  cul- 
tivated lands. 

1811  A.D.  The  thirty-eighth  eruption  was 
announced  on  the  night  of  the  28th  of  December* 
by  the  shock  of  an  earthquake;  and  on  the  31st 
smoke  rose  from  the  cone,  accompanied  by  the 
usual  subterranean  noises.  On  the  1st  of  January, 
1812,  a pyramid  of  fire  and  a column  of  smoke 
shot  up  high  in  the  air  ; and,  at  four  in  the  morning, 
the  lava  flowed  from  the  summit  and  divided  itself 
into  two  streams.  One  soon  stopped,  but  the  other 
continued  to  go  on  towards  Torre  del  Greco,  over 
the  old  lava,  creating  great  alarm  in  the  town. 


ERUPTIONS  OP  VESUVIUS. 


65 

At  noon  it  arrived  within  two  miles  of  the  palace 
of  the  Cardinal,  having  run  three  miles  in  eight 
hours.  On  the  2d,  3d,  and  4th,  new  lava  flowed 
out  over  that  of  the  1st,  but  soon  stopped,  and  this 
eruption  terminated. 

1813  A.  D.  On  the  evening  of  the  24th  of 
December,  a slight  earthquake  occurred  ; and,  the 
next  day,  the  thirty-ninth  eruption  commenced. 
The  mountain  threw  out  liquid  lava,  with  a loud 
crackling  sound,  from  the  summit,  and  from  new 
openings  near  it.  The  ashes,  lapillo,  and  smoke 
ascended  in  the  form  of  a pine,  to  an  immense 
height ; and  the  sun,  seen  through  it,  appeared 
like  the  moon  behind  flitting  clouds,  during  a 
stormy  night.  Ashes  and  pumice  fell,  on  the 
western  side  of  the  mountain,  to  a considerable 
distance,  doing  much  injury  to  the  young  crops, 
and  to  the  shoots  of  the  vines. 

1817  A.D.  The  fortieth  eruption  began  on 
the  22d  December,  and  terminated  on  the  2bth 
of  the  same  month.  From  1813,  small  eruptions 
within  the  crater,  extending  sometimes  to  the  out- 
side, frequently  occurred,  and  at  length  formed 
two  small  cones  on  the  bed  of  lava,  within  the 
great  cone.  Both  of  these  fell  in  on  the  22d,  and 
the  lava  burst  from  the  summit,  one  current  run- 
ning towards  Mauro,  and  another  going  on  to  the 
Pedementina.  The  current  that  took  the  direction 


p 


06  ERUPTIONS  OF  VESUVIUS. 

of  Mauro  broke  out  from  a new  opening  half  way 
up  the  north  side  of  the  cone.  It  ran  down  the 
slope,  and  spread  out  into  a sort  of  lake,  at  the 
eastern  base  of  Somma,  and  thence  descended  into 
the  woods  of  Ottajano,  close  to  the  palace  of  the 
Prince,  and  to  within  a few  feet  of  the  road  which 
leads  from  Bosco  Tre  Case  to  the  town  of  Otta- 
jano ; the  other  stream,  issuing  on  the  south  side, 
also  spread  out  on  the  Pedementina,  and  seemed  to 
menace  Torre  del  Greco ; but,  afterwards,  it 
turned  away  more  to  the  west,  in  a line  with  the 
palace  of  the  Favorita,  which  stands  at  a short 
distance  from  Resina. 

1820  A.D.  The  forty-first  eruption  com- 
menced in  the  middle  of  the  year  1820,  and  lava 
flowed  slowly  and  in  a small  quantity  from  the 
southern  side  of  the  great  cone,  a little  above  the 
Pedementina.  Six  mouths  also  opened  in  the 
north-west  side,  and  six  cones  were  formed  over 
them,  in  a direct  line  along  the  base  of  the  great 
cone.  From  these  lava  was  detruded  towards  the 
Fosso  Vetrana : it  passed  over  that  of  1786,  stop- 
ping in  the  ravine,  at  a few  hundred  yards  below 
the  ruins  of  the  chapel.  During  the  months  of 
October  and  November,  lava  appeared  in  the  great 
crater,  and  red  hot  masses  were  projected  from 
two  small  cones  which  had  risen,  the  largest  to  a 


ERUPTIONS  OF  VESUVIUS.  (>7 

greater  height  than  the  point  of  the  Palo,  and 
about  450  feet  above  the  Java  around  it. 

In  January,  1822,  another  small  cone  rose  on  the 
Atrio  del  Cavallo,  near  the  former  six,  which  threw 
out  much  scoria.  On  the  22d  February  a shock 
of  an  earthquake  was  felt  near  the  mountain,  and, 
soon  after,  a torrent  of  lava  issued  from  the  western 
side  of  the  summit  of  the  crater,  and  flowed  down, 
in  two  streams,  on  the  Atrio  del  Cavallo : they 
there  united  and  ran  towards  the  Punta  della 
Croce,  on  the  Canteroni ; thence  made  a turn  and 
flowed  towards  Resina,  over  the  lava  of  1810.  On 
the  evening  of  the  23d,  the  column  of  smoke 
became  magnificent,  and  a quantity  of  scoria  was 
thrown  out  from  the  small  crater.  This  activity 
continued  on  the  24th  and  26th,  the  lava  appear- 
ing on  the  south-west  summit  of  the  crater,  and  de- 
scending in  six  streams,  all  uniting  on  the  Atrio 
del  Cavallo.  There  were  also  showers  of  ashes 
and  sand,  the  latter  of  which  fell  in  Naples.  On 
the  28th  the  lava  stopped,  after  having  crossed  the 
road  leading  to  the  Hermitage. 

1822  A.D.  The  forty-second  eruption  oc- 
curred in  the  month  of  October.  During  the  early 
part  of  the  month,  the  immense  quantity  of  scoria, 
thrown  out  by  the  small  crater,  raised  the  level  of 
the  internal  plain  very  nearly  to  the  edge  of  the 
great  cone.  On  the  evening  of  the  20th  slight

shocks  of  earthquakes  were  felt  for  some  distance 
around  the  mountain,  and  thick  dark  smoke  rose 
from  the  great  crater.  On  the  21st,  about  three 
p.  m.,  the  lava  suddenly  boiled  over  the  edge  of 
the  crater,  and  ran  down  in  twTo  streams  towards 
Resina  and  the  Canteroni,  but  without  passing 
over  the  Atrio.  At  midnight  immense  columns  of 
smoke  and  fire  rose  from  the  crater,  to  the  height 
of  2000  feet,  while  sand,  as  well  as  melted  lava, 
were  thrown  far  out  on  the  exterior  of  Vesuvius. 
Showers  of  hot  ashes  and  scoria,  which  fell  upon 
Bosco  Tre  Case  and  Ottajano,  created  great  alarm, 
and  drove  the  people  from  their  houses.  The  part 
of  the  crater  opposite  Torre  del  Greco  continued 
in  great  activity  during  the  morning,  and  new 
streams  of  lava  flowed  down  the  western  and 
southern  flanks  of  the  cone.  It  was  remarked 
that  when  the  lava  ceased  to  flow  for  a short  time, 
the  projection  of  smoke  and  melted  matter  greatly 
increased  ; but  decreased  and  became  more  steady 
when  the  lava  began  to  flow  again.  About  mid- 
day a column  of  smoke  rose  to  an  enormous  height, 
spreading  out  like  an  umbrella,  over  the  mountain 
and  its  neighbourhood.  At  two  o’clock  flashes  of 
lightning  were  observed  between  the  cone  of 
Vesuvius  and  the  convent  of  the  Camaldoli,  dart- 
ing through  the  smoke  and  far  along  the  sky  above 
it.  The  lava  flowed  into  the  Fosso  Grande,  and

over  the  Piano  delle  Ginestre  towards  Resina, 
occupying  more  than  half  the  space  between  the 
Fosso  Bianco  and  Fosso  Grande,  and  threatening 
to  destroy  Portici ; but,  having  approached  to 
within  a mile  and  a half  of  the  church  of  Resina, 
it  began  to  cool,  and,  soon  after,  it  ceased  to  flow. 

In  the  mean  time  the  eastern  side  of  the  moun- 
tain became  more  active ; lava  flowed  down  in 
three  currents  towards  Bosco  Tre  Case  and  the 
Viuli : the  third  stream  passed  over  that  of  1810. 
During  the  night  the  scene  was  very  extraordinary 
and  beautiful,  from  the  constant  showers  of  melted 
lava  thrown  to  an  immense  height,  and  the  electric 
fire  playing  magnificently  in  the  midst  of  the  illu- 
minated smoke.  On  the  23d  the  ejection  of  melted 
matter  continued,  but  with  less  force,  and  the 
streams  on  the  eastern  side  had  ceased  to  move, 
except  the  one  that  ran  towards  Mauro  ; this, 
however,  continued  flowing  during  the  day,  and 
reached  the  Piscinella,  near  the  palace  of  the 
Prince  of  Ottajano.  On  the  24th  showers  of  sand 
were  thrown  out,  darkening  the  air  so  much,  that, 
in  some  places,  people  were  obliged  to  light  their 
lamps.  The  mountain  was  completely  enveloped 
in  dense  clouds  of  vapour  and  smoke ; and  on  the 
27th,  torrents  of  water,  washing  down  sand  and 
ashes,  inundated  the  country  about  Massa  and 
St.  Sebastiano,  doing  much  injury,  and  creating 


70

great  terror  among  the  inhabitants.  The  eruption 
then  ceased,  and  the  mountain  resumed  a state  of 
tranquillity. 

The  summit  of  the  crater  was  much  changed  by 
the  eruption,  having  lost  several  hundred  feet  of 
its  height,  on  the  side  towards  Torre  del  Greco, 
the  northern  side  remaining  in  nearly  its  former 
state  ; so  that  the  crater  appeared  as  though  cut 
obliquely  from  north  to  south.  The  Pedementina, 
at  the  western  and  southern  side  of  the  cone,  had 
been  raised  above  two  hundred  feet  by  new  lava, 
the  material  ejected  from  the  cone,  and  ashes 
washed  down  by  the  rains. 

The  Canale  dell’  Arena,  however,  on  the  northern 
side  of  the  cone,  was  only  very  slightly  raised  by 
the  scoria  ejected  from  the  crater  and  the  ashes 
brought  down,  no  lava  having  flowed  in  that  di- 
rection. 

The  depth  of  the  cavity  of  the  crater  was  above 
eight  hundred  feet,  and  its  form  was  that  of  an 
irregular  ellipsis,  its  greater  axis  lying  from  s.  w. 
to  n.  e.  The  ridges  of  its  edge  sloping  from  its 
summit,  inwardly  towards  each  other,  were  very 
nearly  united  at  the  bottom,  leaving  only  a small 
circular  plain,  covered  with  large  masses  of  scoria. 

1831  A.  D.  The  forty-third  eruption.  In 
March,  1827,  a small  cone,  formed  on  the  plain  at 
the  bottom  of  the  gulf  towards  the  n.  e.  side, 


ERUPTIONS  OF  VESUVIUS.

began  to  eject  scoria  and  lava,  throwing  them  up 
nearly  one  third  of’  the  height  of  the  main  crater. 
This  small  cone  continued  in  a state  of  constant 
activity  until  the  November  following,  when  the 
ejection  of  scoria  became  occasional  only.  This 
process  went  on  during  1828  and  1829,  sometimes 
with  greater,  at  others  with  less  force ; and  the 
level  of  the  lava  was  raised,  on  the  s.  w.  side,  to 
within  120,  and  on  the  s.  e.  side  to  within  eighty 
feet  of  the  edge,  being  very  nearly  even,  intersected, 
however,  by  two  large  crevices  ; but  the  ejection 
of  matter  from  the  cone  was  seldom  so  violent  as 
to  prevent  persons  from  climbing  to  its  summit. 

In  May,  1880,  the  small  cone  was  150  feet  above 
the  level  of  the  lava  : it  had  a circular  crater  thirty 
feet  deep,  shaped  like  a basin,  and  at  night  the 
molten  scoria  was  often  visible  on  its  surface.  A 
bright  blue  flame  sometimes  suddenly  appeared, 
and  spread  out  several  feet  at  the  bottom  of  the 
crater,  lasting  for  a few  seconds,  during  which  the 
scoria  and  loose  stones,  occupying  a space  of  six 
or  eight  feet  in  circumference,  rolled  about,  as  if 
stirred  round  by  some  force  from  below  : the  flame 
was  soon  extinguished,  and,  at  the  same  instant, 
the  part  that  had  been  in  motion  was  shot  up  high 
into  the  air,  with  a whizzing  noise  : most  of  it  fell 
back  to  the  spot  whence  it  had  been  thrown,  and 
the  rest  fell  about  on  the  sides  of  the  small  cone,

or  was  carried  by  the  wind  on  to  the  lava  around 
it,  sometimes  even  to  the  edge  of  the  great  crater. 
In  November  the  ejection  of  scoria  became  violent, 
and  streams  of  molten  matter  flowed  from  the  base 
of  the  small  cone,  by  which  the  inclination  of  the 
lava  and  the  appearance  of  the  inside  of  the  crater 
were  greatly  altered  ; for  on  the  s.  w.  side  it  was 
raised  to  within  fifty  feet,  and  on  the  s.  e.  side  to 
within  thirty  feet  of  the  edge.  The  small  cone 
was  also  much  increased  in  height,  and,  though  at 
first  circular,  had  become  oblong  : the  greater  axis 
was  north  and  south,  nearly  at  right  angles  with 
that  of  the  main  crater  ; on  the  south  of  it,  five 
minor  cones  had  risen,  covered  with  various  shades 
of  yellow,  blue,  and  green  ; all  threw  out  scoria  in 
a state  of  fusion,  accompanied  by  a dense  yellowish 
white  vapour,  which  rushed  out  with  a noise  like 
that  of  steam  escaping  from  the  safety  pipe  of  a 
boiler.  Although  the  surface  of  the  lava  had 
cooled  and  become  black,  yet,  a few  inches  be- 
neath, it  was  red  hot,  and  a stick  pushed  into  any 

N 

crevice  took  fire. 

By  the  middle  of  January,  1831,  it  had  become 
cool,  and  only  three  of  the  smaller  cones  remained 
in  activity  : they  and  the  greater  one  continued 
occasionally  to  eject  melted  matter  during  the 
summer,  until  the  14th  August.  About  ten  o’clock 
in  the  morning  of  that  day  a slight  shock  of  an 


ERUPTIONS  OP  VESUVIUS. 


73 


earthquake  was  felt  in  Resina  and  the  neighbour- 
ing* towns,  and  a large  heavy  column  of  sable 
smoke  rose  from  the  crater.  On  the  15th  a con- 
siderable emission  of  lava  proceeded  from  the  base 
of  the  small  cone  and  ran  towards  the  s.  w.  edge 
of  the  crater,  in  a winding  course,  while  several 
smaller  streams  flowed  about  in  all  directions, 
within  the  crater.  On  the  18th  a wide  river  of 
lava,  in  a state  of  extraordinary  liquidity,  issued 
from  the  small  cone,  covering  up  inequalities,  and 
raising  the  whole  level,  on  the  western  side,  to 
within  fifteen  feet  of  the  edge  ; the  small  cone  also 
was  very  active,  throwing  stones  of  a large  size 
hundreds  of  feet  into  the  air.  Large  crevices  were 
formed  in  several  directions  across  the  lava  ; and 
in  the  night  of  the  22d  four  new  cones  rose  near 
the  six  already  mentioned.  Nearly  the  whole  mass 
of  lava  within  the  crater  seemed  to  be  almost  in  a 
state  of  fusion  ; the  number  of  brilliant  spots  where 
it  was  completely  melted  making  it  appear  like  an 
illuminated  city.  The  crater  was  now  full  on  the 
western  side,  the  lava  threatening  to  flow  over  the 
path  on  the  outside  of  the  cone  ; but  on  the  s.  e. 
side  it  still  wanted  four  feet  of  being  even  with 
the  edge.  The  level  of  the  lava  was,  however, 
irregular,  rising  several  feet  higher  on  the  western 
side  of  the  small  cones  than  on  the  other,  and 
descending  in  terraces  or  tables,  a few  feet  in 


74  ERUPTIONS  OF  VESUVIUS. 

thickness,  towards  the  edge  of  the  crater.  Be- 
tween the  eastern  side  of  the  cones  and  the  edge 
of  the  crater  it  formed  a regular  concave  surface, 
the  deepest  point  being  about  twenty  feet  below 
the  level  of  the  edge.  Two  mouths  had  opened 
in  the  small  oblong  cone,  both  throwing  out  stones 
and  smoke,  sometimes  white,  sometimes  loaded 
with  sand  and  dust;  but  these  ejections  did  not 
take  place  with  regular  alternations  from  each 
mouth  ; one  sometimes  threw  out  stones,  while 
the  other  emitted  only  vapour ; then  they  changed 
for  a few  moments,  and  then  threw  out  stones 
together  ; and  again,  when  the  principal  cone  was 
ejecting  scoria,  one  or  two  of  the  smaller  cones 
nearest  it  ceased  to  emit  vapour  with  their  ordinary 
force  and  peculiar  noise,  but  recommenced  as 
soon  as  the  jet  from  the  greater  cone  had  been 
effected. 

This  eruption  of  matter  continued  until  the  18th 
of  September,  when  the  lava,  which  had  two  days 
before  risen,  in  some  parts,  to  a height  of  fifteen 
feet  above  the  s.e.  edge  of  the  crater,  began  to 
flow  over  on  that  side,  and  having  run  down  six- 
teen feet,  in  a stream  fourteen  feet  wide,  it  cooled. 
The  same  day,  about  two  o’clock,  another  stream 
to  the  north  of  this  one  reached  the  edge  and 
flowed  over. 

The  appearance  of  the  interior  of  the  crater  was 


ERUPTIONS  01-  VESUVIUS. 


7-5 

slightly  changed : the  fissures  had  been  widened, 
and  formed  a curve  from  n.n.e.  to  w.n.w.  round 
the  outside  of  the  small  craters,  one  of  which,  ex- 
cepting only  its  northern  side,  had  fallen  to  pieces. 
Its  remains  exhibited  a front  of  perfect  columnar 
basaltic  lava  twenty  feet  high:  the  part  which  had 
fallen  was  a heap  of  cubic  masses  of  lava  and  scoria, 
tinged  with  beautiful  shades  of  green.  The  whole 
space  enclosed  by  these  fissures  was  one  ground  of 
bright  yellow,  with  occasional  patches  and  streaks 
of  red. 

On  the  20th  it  was  observed  that  the  lava  had 
flowed  two  hundred  feet  down  the  s.e.  exterior  of 
the  great  cone,  and,  continuing  to  run  with  rapi- 
dity, it  took  the  direction  of  JBosco  Reale.  On 
the  27th  it  ceased  to  flow  in  the  same  course,  but 
divided  on  the  Pedementina,  and,  winding  round 
the  base  of  the  cone  towards  the  west,  swept  on- 
wards to  the  Vocoli,  or  craters  of  the  eruption  of 
17bO,  over  a stream  emitted  in  1822;  but  it  stopped 
within  half  a mile  of  them  on  the  evening  of  the 
30th.  The  stream  then  resumed  its  original  direc- 
tion, and,  during  the  early  part  of  October,  flowed 
steadily  and  slowly  onward  till  it  reached  the  edge 
of  the  Pedementina.  On  the  evening  of  the  20th 
the  eruption  attained  its  climax;  the  column  of  fire, 
which  rose  from  the  crater,  was  immense  and 
very  splendid  ; and  the  lava  bursting  out  from  the

north  side  of  the  small  cone  ran  towards  the 
western  edge  of  the  great  crater,  which  it  soon 
reached,  and,  enveloping  the  large  stone  that  stood 
at  the  point  where  the  path,  which  leads  up  the 
side  of  the  cone,  arrives  at  the  top,  flowed  over, 
about  forty  feet  to  the  left  of  this  spot ; and  on  the 
21st  it  stopped,  having  run  down  in  a stream  260 
feet  in  length,  and  about  twenty  in  breadth.  Dur- 
ing the  night  of  the  22d  the  small  cone  underwent 
a great  alteration ; for  the  sides  to  the  north  and 
south  being  blown  away,  it  there  lost  more  than 
half  its  height,  while  on  the  west  and  east  it  received 
so  great  an  accumulation  that  it  became  visible  at 
Naples,  its  western  side  being  the  highest.  Within 
its  edge  there  were,  on  the  28th  of  October,  five 
mouths  of  greater  or  less  depth,  varying  from 
twenty  to  sixty  feet,  from  one  of  which  only  a 
white  vapour,  impregnated  with  muriatic  or  sul- 
phuric acid,  was  emitted:  the  north  side  appeared 
one  mass  of  solid  lava,  the  other  was  covered  with 
scoria,  ashes,  and  dust.  The  whole  crater  of  the 
great  cone  then  became  tranquil. 

A few  slight  explosions,  from  the  small  cone, 
occurred  during  November  and  the  early  part  of 
December,  and  changes  continually  took  place  in 
the  surface  of  the  plain  of  the  great  crater : cre- 
vices were  opened  on  one  day,  and  closed  again 
the  next : platforms  were,  in  one  place,  raised,  in 


ERUPTIONS  OF  VESUVIUS.

another  depressed ; and  the  small  cones  were,  by 
degrees,  broken  down  : all  indicating  that  some  vio- 
lent operation  was  actively,  though  silently,  going 
forward  within  the  depths  of  the  volcano. 

On  the  20th  of  December  a column  of  smoke, 
accompanied  by  frequent  showers  of  stones,  rose 
from  the  small  cone ; and  a stream  of  lava  flowed  from 
its  south-eastern  side,  in  the  direction  of  that  point 
which  is  above  Torre  del  Greco,  and  afterwards 
followed  the  curve  of  the  crater.  On  the  22d  the 
volume  of  smoke  and  the  jet  of  stones  increased, 
and  the  fissure  around  that  great  platform,  already 
described  as  being  raised  above  the  level  of  the 
lava  to  the  south  of  the  small  cone,  widened  so  as  to 
become  impassable,  except  at  one  point ; making  it 
a peninsula,  which  presented  a perpendicular  front 
fifteen  feet  above  the  outer  edge  of  the  crevice.  The 
opening  on  the  exterior  of  the  small  cone  had  been 
choked  up  ; but  the  three  interior  vents  threw  out 
molten  lava  in  large,  shapeless  masses,  or  in  broad 
lumps,  of  the  size,  and  moulded  into  the  form,  of 
turkey’s  eggs.  These  were  driven  out  with  a whiz- 
zing noise  or  loud  report ; and  the  effect  produced 
by  the  red  hot  matter  at  the  moment  of  expulsion 
resembled  that  of  the  bursting  of  a shell,  or  the 
discharge  from  a large  mortar  when  fired. 

Lava  had  also  issued  from  the  n.e.  side  of  the 
small  cone,  and  had  wound  slowly  round  its  base, 


78 


ERUPTIONS  OF  VESUVIUS. 


towards  the  spot,  at  the  western  edge  of  the  crater, 
where  the  stream  flowed  out  in  October.  Five 
small  fumaroli,  close  together,  in  a line  with  each 
other,  and  rising  three  feet  above  the  middle  of 
this  stream,  shot  out  pieces  of  lava,  of  the  size  of 
small  cannon  balls,  about  five  feet  into  the  air, 
with  a report  like  that  of  a pistol. 

On  Christmas  day,  between  ten  and  eleven  a.m., 

%/ 

the  lava  from  the  s.e.  side  of  the  cone  arrived  at 
the  edge  of  the  crater,  where  the  great  stone  stood, 
and  ran  rapidly  down  over  the  path  by  which, 
previously,  it  was  customary  to  ascend.  At  two 
o’clock  it  was  half  way  down  the  cone,  and,  as 
observed  at  night  from  Naples,  produced  a beauti- 
ful effect.  The  vapour  from  the  lava,  and  the 
smoke  from  the  cone,  becoming  heavy,  sank  down 
upon,  and  enveloped  the  burning  torrent,  hiding 
it  from  view ; then,  suddenly  blown  away,  it  would 
disclose  the  fiery  streak,  which  seemed,  from  the 
darkness  that  reigned  around  it,  to  shoot  up  into 
the  air,  as  if  it  were  some  enormous  rocket. 

Half  way  down,  the  mass  turned  towards  Resina, 
leaving  the  path,  and  running  with  great  rapidity 
to  the  foot  of  the  cone,  where  it  arrived  before 
midnight.  On  the  26th  of  December,  at  noon,  it 
had  flowed  twelve  hundred  feet  from  the  base  of 
the  cone,  making  altogether  a distance  of  3600 
feet  in  twenty-six  hours.  At  that  time  it  was 


ERUPTIONS  OF  VESUVIUS. 


79 


advancing  at  the  rate  of  ten  feet  an  hour,  in  three 
streams,  having  a front  of  280  feet,  over  the  old 
lavas  of  I7C7, 1775,  1810,  and  1822.  At  two  o’clock 
the  stream  from  the  northern  side  reached  the 
edge  of  the  crater,  flowed  over  the  lava  of  October 
down  a third  of  the  cone,  and  there  joined  the 
other  current. 

During  the  night  of  the  27th  it  rained  heavily 
at  Naples;  and  next  morning  the  upper  part  of 
Vesuvius  was  seen  to  be  covered  with  snow,  the 
hot  stream  being  marked  out  by  the  black  line 
which  extended  from  the  top  to  the  bottom  of  the 
cone. 

In  the  mean  time  the  small  cone  became  com- 
paratively tranquil,  seldom  throwing  out  any  lava, 
though  it  still  emitted  smoke.  On  the  first  day  of 
the  year  the  explosions  from  it  recommenced  with 
great  violence,  and  much  scoria  was  ejected.  The 
lava  continued  to  flow  slowly,  at  the  upper  end, 
and  did  not  entirely  stop  till  the  12th,  though  the 
lower  extremity  ceased  to  advance  on  the  10th  of 
January ; the  stream  being  then  7<500  feet  long, 
and  280  feet  wide.  The  lava  was  still  warm  on 
the  28th  : a thermometer  placed  on  the  slope  of 
the  new  bed  rose  to  106  Fall. ; and  scoria,  taken  a 
few  inches  from  below  the  surface,  was  too  hot  to 
be  held  in  the  hand.  On  the  same  morning  that 
the  lower  part  of  the  stream  stopped,  the  cone 


80 


ERUPTIONS  OF  VESUVIUS. 


became  perfectly  quiet,  and  remained  so  till  the 
18th  of  February,  when  numerous  and  violent 
shocks,  accompanied  by  a noise  like  the  roaring 
of  the  sea  during  a storm,  were  felt  on  the  moun- 
tain, and  they  were  renewed  sew.  .1  times  on  the 
following  night.  The  same  evening  two  circular 
apertures,  forty  feet  in  circumference,  and  as  many 
deep,  opened  within  the  small  cone  nearly  in  the 
same  place  where  those  of  last  December  existed  ; 
and  from  them  was  thrown  up  a column  of  white 
smoke,  red  hot  scoria,  and  ashes : these  latter, 
carried  by  the  wind,  spread  over  the  flank  of  the 
old  cone  in  the  direction  of  the  Piano  del  Ginestre. 
The  smoke,  strongly  charged  with  sulphur  and 
marine  salt,  beating  against  the  southern  wall  of 
the  crater,  deposited  them,  covering  the  whole  with 
a cake  of  a yellow  and  a white  colour  intermixed. 
The  vapour  which  rose  from  all  parts  of  the  crater 
was  so  strongly  charged  with  acids  that  it  was 
impossible  to  breathe  in  it  for  more  than  a few 
seconds. 

A stream  of  lava  broke  out  on  the  20th  from 
that  part  of  the  crater  on  which  the  small  cones 
rose  in  August  last,  and,  extending  over  the  south- 
ern portion  of  the  plain,  covered  the  old  lava, 
filling  up  the  inequalities  and  making  a perfectly 
level  surface.  Near  the  point  whence  the  lava 
issued,  twenty  feet  from  the  remains  of  the  small

cones,  liquid  lava  bubbled  lip  like  bitumen  in  cir- 
cular waves,  in  the  same  manner  as  in  some  orna- 
mental fountains,  the  water,  playing  from  a centre, 
curls  and  rolls  down  over  fanciful  masonry : when 
they  had  cooled  * .1  become  hard,  they  resembled 
a coil  of  the  thickest  cable. 

An  earthquake,  having  an  oscillation  from  south 
to  north,  and  accompanied  by  a crackling  sound, 
which  resembled  the  rumbling  of  carriages  over  a 
rough,  uneven  pavement,  was  felt  at  Pozzuoli  and 
the  surrounding  district,  at  one  o’clock  in  the 
afternoon  of  the  21st,  and  though  slight  at  that 
town,  was  considerable  in  other  places,  particularly 
at  Monte  St.  Angelo,  throwing  down  some  walls, 
and  doing  much  inj  ury  to  several  cottages.  About 
the  same  time,  the  stream  of  lava  received  a great 
augmentation  and  stimulus,  so  that  it  passed  out 
from  the  great  crater,  at  the  spot  where  the  other 
lava  had  last  issued,  and  ran  down  its  southern 
edge,  arriving  before  morning,  at  the  base  of  the 
cone.  Owing  to  the  steepness  of  that  part  of  the 
cone  on  which  it  flowed,  little  scoria  formed  upon 
its  surface,  so  that  it  had  a beautiful  effect,  the 
bright  streak  of  fire,  sparkling  in  the  darkness  like 
a meteor  ; and  sometimes,  when  a fresh  and  sudden 
impulse  was  given  to  the  current,  a billow',  more 
luminous  and  brilliant  than  the  rest  of  the  fiery 
mass,  and  darting  forward  in  long  rapid  flights,  slid

or  shot  down  the  stream.  The  small  cone  con- 
tinued to  eject  red-hot  matter  and  a quantity  of 
thick  smoke,  which  hanging  over  the  mountain  in 
large  round  volumes  heaped  one  above  the  other, 
looked  like  an  immense  cauliflower  during  the  day, 
and  at  night,  illuminated  by  reflection  from  the 
burning  lava,  presented  a singular  appearance,  rich 
in  many  changes  of  form  and  varieties  of  colour. 

On  the  25th  a stream  separating  within  the  cra- 
ter from  the  one  which  had  been  flowing  for  some 
days,  advanced  to  the  edge  in  two  branches  and 
ran  over ; one  of  these  stopped,  after  proceeding 
half  way  down  the  cone,  but  the  other  moved 
rapidly  towards  the  base  in  the  direction  of  the 
Punta  delle  Crocelle  on  the  Canteroni.  During 
the  26th  and  27th  the  projection  of  matter  from  the 
small  cone  and  the  emission  of  lava  continued 
without  cessation,  and  on  the  evening  of  the  latter 
day,  the  stream  which  ran  towards  the  Canteroni, 
rolled  down  the  cone  with  great  rapidity,  covering 
the  stones  at  which  it  was  customary  to  leave  the 
mules ; its  width  and  height  making  it  a magnifi- 
cent object,  which,  together  with  the  original 
stream  flowing  in  the  contrary  direction,  produced 
a very  splendid  effect.  This  new  stream  continued 
to  flow  for  a few  days  gradually  decreasing  in  force, 
and  on  the  22d  it  entirely  stopped.  The  stream 
which  came  over  the  edge  on  the  21st  ran  slowly

down  till  the  5th,  when  it  ceased  to  How ; on  the 
7th,  however,  another  issued  to  the  north  of  the 
rest,  but  only  flowed  two  days. 

On  the  evening  of  Thursday  the  8th,  at  fourteen 
minutes  past  seven  o’clock,  an  earthquake  was 
felt  at  Naples,  and  a second  shock  succeeded  at 
two  o’clock  the  following  morning ; both  had  an 
oscillation  proceeding  from  south  to  north,  but 
were  slight,  unattended  by  any  subterranean 
sounds,  and  did  no  damage  in  the  city,  or  in  its 
environs.  The  weather  had  been  stormy  through- 
out the  day,  and  towards  night  the  wind  blew  with 
great  violence  from  the  south,  often  breaking  into 
sudden  and  tremendous  gusts.  The  shocks  were 
not  confined  to  the  bay  of  Naples,  they  extended 
through  part  of  Calabria,  and  the  beautiful  town 
of  Catanzaro,  its  capital,  built  on  a hill  eight  miles 
distant  from  the  sea,  was  laid  in  ruins  by  the  first 
convulsion,  nearly  at  the  same  hour  at  which  its 
shock  was  felt  at  Naples,  but  the  particulars  of  this 
catastrophe  have  not  yet  been  received.  It  is 
not  the  first  time  that  this  city  has  suffered  from 
similar  visitations  ; in  1626  it  was  nearly  destroyed, 
and  in  the  great  earthquake  of  1783,  a considerable 
part  was  thrown  down  and  otherwise  injured. 

The  Volcano,  however,  remained  in  a tranquil 
state ; but  a constant  emission  of  smoke  and  of 
melted  scoria  has  continued  to  take  place.  The

mass  of  vapour  ejected  sometimes  settles  like  mist 
on  the  top  of  the  cone,  sometimes  rises  aloft  like  a 
pyramid,  or  in  a funnel-shaped  form,  and  often, 
blown  away  by  the  strong  northerly  breezes  pre- 
vailing at  this  season  of  the  year,  stretches  across 
the  sky  in  thin  straggling  layers,  or  in  a dark  line, 
which  lengthens  out,  and  is  confounded  with  the 
horizon.

APPENDIX. 


Since  the  preceding  sketches  of  Vesuvius  were  printed, 
two  eruptions  have  made  a material  change,  not  only 
within  the  great  crater,  but  also  on  the  exterior  of  the 
cone  at  that  part  where  it  was  usual  to  ascend. 

In  the  first  eruption,  which  commenced  on  Christmas 
Day,  the  lava  flowing  over  the  great  stone  at  the  upper 
end  of  the  path,  descended  from  this  point  and  spread  into 
several  long  and  narrow  ridges  of  scoria,  each  having  a 
hollow  in  the  middle  that  served  as  a channel  through 
which  the  molten  lava  ran;  and  when  it  had  ceased  to  flow, 
they  resembled  the  dried  up  beds  of  mountain  rivulets. 
These  ridges  cover  the  old  path  as  far  as  half  way  down 
the  cone,  and  there  uniting  into  one  large  mass  or  principal 
stream,  turn  off  to  the  right,  and  continue  down  the  slope 
to  the  Atrio.  This  ledge,  from  the  accumulation  and  con- 
tinual piling  up  of  the  scoria,  forms  a lofty  bank,  having 
less  inclination  than  the  slope  of  the  cone,  and  looks  like 
an  embankment  made  to  carry  a canal  or  road  over  a 
valley.  Thus  far  there  were  three  courses  for  the  lava, 
but  on  arriving  at  the  Atrio,  they  divided  into  several 
others,  forming  a wide  flat  mound,  and  proceeded  towards 
Resina,  in  a line  parallel  with  the  Canteroni.  In  the 
annexed  sketch  I have  attempted  to  give  an  idea  of  the 
appearance  which  the  front  of  the  bank  has,  while  pushed

APPENDIX. 


forward  by  the  fluid  material  within  it.  Near  the  bottom, 
masses  of  soft  lava  are  twisted  and  squeezed  out  from 
under  the  incumbent  matter  like  dough  from  the  kneading- 
trough  ; higher  up,  lumps  of  scoria,  red-hot,  but  no  longer 
soft,  detach  themselves,  and  roll  down;  smaller  pieces 
crumbling  away  from  the  top  pour  down  over  the  rest, 
so  that  the  front  is  not  perpendicular,  but  has  a slight 
inclination. 

A path  has  been  made  along  the  northern  edge  of  the 
new  lava,  but  it  is  much  more  rough,  steep  and  difficult 
than  the  old  one.  On  reaching  the  top,  three  hundred 
feet  to  the  left  of  the  point,  where  the  ascent  formerly  ter- 
minated, the  recent  matter  is  found  piled  up  in  large  slabs 
and  irregular  pieces,  which  were  raised  higher  than  the 
edge  of  the  crater ; indeed,  the  whole  of  it  in  this  part  of 
the  interior,  rose  with  a considerable  inclination  towards 
the  small  cone  and  towards  the  insulated  platform,  which 
was  nearly  enveloped  by  the  surrounding  lava.  The  minor 
craters  or  fumaroli  had  become  nearly  confounded  with 
the  rest,  and  their  remains,  as  also  the  whole  of  the  plat- 
form, were  covered  with  a coating  of  sulphur. 

The  base  of  the  small  cone  had  greatly  increased  in 
circumference ; within  it  were  two  craters,  the  first  a large 
one  forming  a segment  of  a circle,  the  curve  sloping 
towards  the  bottom,  which  was  eighty  feet  deep,  and  only 
a few  feet  in  width ; the  diameter  of  this  segment  was  a 
perpendicular  line  of  compact  lava,  of  which  the  whole 
western  side  of  the  cone  was  formed.  A second  orifice 
was  a smaller  but  similar  segment,  and  was  only  thirty 
feet  deep.  Three  cracks  extended  across  a narrow  level 
space  between  these  mouths  and  the  eastern  side,  which 
was  much  lower  than  its  opposite ; it  was  round  at  the  top, 
and  sloped  with  a rapid  declivity  to  the  plain  of  lava. 
From  these  cracks  escaped  an  almost  invisible  vapour

highly  charged  with  acid,  and  at  their  edges  various  salts 
were  sublimed  in  efflorescences  of  beautiful  colours.  On 
the  north  the  exterior  was  excessively  steep,  but  on  the 
south  it  sloped  gradually  down  to  the  remains  of  the  plat- 
form, which  still  presented  an  upright  front  towards  the 
east  and  south,  but  the  fissure  was  nearly  filled  with  scoria 
ejected  from  the  cone.  The  part  of  the  great  crater  be- 
tween this  and  its  eastern  edge,  was  the  same  as  it  was  in 
October,  but  so  great  a quantity  of  marine  salt  had  eva- 
porated through  its  crevices,  that  some  people  from  Torre 
del  Greco  had  collected  several  sacks  of  it. 

Within  the  crater,  at  a short  distance  from  the  point 
where  the  lava  passed  over  its  edge,  several  large  oblong 
slabs  of  lava  were  joined  together  in  a convex  form ; or 
rather,  their  sides,  inclining  towards  each  other,  supported 
a central  and  horizontal  table ; the  fourth  side  was  split  in 
two,  and  through  the  crack  the  stream  rushed,  as  if  from 
under  a ruined  arch. 

The  lava,  which  ran  from  the  western  side  of  the  cone, 
at  the  end  of  last  month,  has  also  made  an  alteration  in 
the  appearance  of  its  exterior.  The  first  stream  which 
issued  on  the  21st,  after  having  flowed  in  a straight  line 
half  way  down  the  cone,  at  a few  yards  to  the  south  of  the 
streams  of  last  January,  united  with  them,  connecting  the 
extremities  of  the  curve  which  they  formed.  The  stream 
which  came  over  on  the  25th,  to  the  north  of  the  others, 
flowed  down  towards  the  spot  where  it  was  customary  to 
commence  the  ascent  on  foot,  and  destroyed  the  lower  part 
of  the  path,  hitherto  untouched  by  any  of  the  streams.  Of 
the  two  which  ran  down  on  the  27th,  one  flowed  in  the 
channel  and  took  the  course  of  the  last,  completely  covered 
the  path,  buried  the  large  blocks  at  the  place  where  the 
mules  used  to  be  left,  and  then  passed  two  hundred  feet 
lower  down : the  second,  to  the  north  of  the  other,  ad-

vanced  about  the  same  distance  from  the  base  of  the  cone 
toward  the  Fosso  Vetrana,  and  then  divided  into  two 
branches,  one  of  which  ran  towards  the  Punta  delle  Cro- 
celle,  the  other  towards  the  Somma,  both  extending  more 
than  a hundred  and  fifty  feet  from  the  point  of  their  separ- 
ation, and  forming  a semicircular  front  of  brown  scoria, 
varying  from  ten  to  fifteen  feet  in  height,  round  the 
northern  extremity  of  which  the  present  path  for  the  mules 
winds,  and  then  follows  the  ridge  formed  by  the  stream,  to 
the  base  of  the  cone.  The  new  footpath  commences  about 
half  way  between  the  old  one  and  the  cones  of  1820,  lead- 
ing, with  very  little  deviation,  up  to  the  summit ; it  is  con- 
sequently steep  and  very  fatiguing,  particularly  at  one 
place  where  it  passes  for  some  distance  through  deep  sand. 
The  interior  of  the  crater  towards  this  side  again  presents 
a different  aspect ; the  plain  is  much  raised,  uneven,  and 
covered  with  hillocks  of  lava,  piled  against  each  other  in 
various  angles,  with  misshapen  lumps  of  scoria  heaped  up 
between  them,  and  the  tabular  mass  is  almost  hidden  by 
different  currents  which  flowed  over  and  around  it.  Only 
one  stream  remained  running  on  the  7th  of  March,  rising 
up  at  the  point,  where  the  new  path  arrives  at  the  edge, 
and  the  compact  material,  in  rolling  away,  was  drawn  out 
into  a stringy  form,  making  a noise  like  that  of  wax  when 
melting.  The  height  of  the  small  cone  was  diminished  on 
its  western  side,  but  had  increased  on  all  the  others  from 
the  scoria  ejected,  and  its  circumference  was,  from  the 
same  cause,  greatly  enlarged  : snow  lay  thick  on  its  exterior, 
while  clouds  of  smoke  and  heavy  showers  of  red-hot  matter 
were  thrown  from  its  interior,  and  it  may  be  supposed  that 
so  strange  a contrast  gave  it  an  interesting  as  well  as  a most 
remarkable  appearance. 

The  lava  on  the  southern  side  of  the  crater,  though  also 
raised,  still  remains  level,  and  the  platform  there  presents

Near  the  place  where  the  lava  lose 
discovered  a beautiful  and  very  singular  archec  gr  , 
formed  by  a gigantic  bubble  of  lava.  The  aici  was  com 
;:;i;  of  a thin  layer  or  cake  of  lava,  from  eight  inches  to 
a foot  in  thickness,  and  the  open  part  or  mouth  had 
fallen  in,  but  had  been  blown  outwards;  the  e gcs 
“ t,  which  remained  standing,  were  covered  with  white, 
m-een  and  light-blue  encrustations.  The  width  of  ie 
whole  was  twenty-four  feet ; that  of  the  opeimig,  fourteen; 
the  depth  from  the  margin  to  the  level  withm,  five  t 
height  of  the  arch  from  the  internal  level,  fifteen ; and  the 

length  inwards  twenty-five  feet. 

The  interior  was  coated  with  pure  salt  in  minute  crysta  , 
thickly  strewn  with  patches  of  bright  green,  and  stalactites 
of  salt,  of  the  same  colour,  hung  from  various  parts.  Tim 
t tom  of  the  interior  was  level,  but  curled  and  twisted 
il  numberless  ripples,  apparently  caused  by  two  ~ 
which  flowed  through  it,  one  from  the  centre  and  the  other 
from  the  right  side,  both  of  which  had  united  and  made 
dll.  exit  through  the  left;  the  whole  was  o a co  our  be-

intense,  as  to  preclude  the  possibility  ot  descenc  ing  in  o 1 ,

without  danger  or  annoyance.
